Barcelona 3-1 Arsenal - Bayern Munich 4-2 Juventus AET: Uefa Champions League last 16 as it happened

That is all from us for now, but we will be back tomorrow night to bring you live coverage of a Europa League double-header as Tottenham look to reverse a 3-0 deficit against Borussia Dortmund at White Hart Lane and Manchester United welcome rivals Liverpool to Old Trafford.

Until then, goodnight.

Here is your lineup for the quarter-finals of the 2015-16 Champions League:

Real Madrid

Wolfsburg

Benfica

Paris Saint-Germain

Manchester City

Atletico Madrid

Barcelona

Bayern Munich

The draw for the next round is due to take place in Nyon, Switzerland at 11.00 GMT on Friday 18 March. We will bring you live coverage of that right here on IBTimes UK.

No need for penalties in the end as Bayern leave it late to book their place in the last eight of the Champions League for the 15th time in their illustrious history. Juventus were extremely good early on, pressing high and relying on the likes of Morata to force defensive mistakes.

Guardiola's side took control late on, however, and probably deserved to go through on the balance of play. Both legs of this tie were hugely entertaining, it must be said.

End of extra-time

Bayern Munich 4-2 Juventus (6-4 on aggregate)

Juventus are out of the Champions League

Another great opportunity for Juventus to reduce the arrears is spurned as Neuer saves Bonucci's header. One minuted of added time to play.

How have Juventus not scored there? Pogba lays it on a plate with a cross for Mandzukic, but his close-range effort is parried by Neuer and Sturaro somehow blasts the rebound into row z.

Feelings have been running high all night between these two sides. Sturaro and Bernat are both booked for squaring up to each other after a rather innocuous foul.

And that, as they say, is that.

After a rare Juventus attack breaks down, Vidal passes to Coman and theJuventus loanee sprints forward into acres of space before cutting inside Bonucci and punishing his parent club with a wicked curled shot that flies past Buffon and in.

Goal: Bayern Munich 4-2 Juventus (Kingsley Coman)

My word how the momentum has swung during the two legs of this captivating tie. From 2-0 down, Bayern hit back to take the lead. Costa's cross is headed away by Evra but only as far as Thiago, who exchanges passes with Muller before slotting under Buffon.

Is that the decisive goal?

Goal: Bayern Munich 3-2 Juventus (Thiago Alcantara)

The final 15 minutes have begun. Can either of these teams find a winner or are we destined for the lottery of a penalty shoot-out?

Half-time in extra-time

Bayern Munich 2-2 Juventus (4-4 on aggregate)

Pereyra is fouled by Vidal on the near side and the fourth official signals one minute of added time.

Pereyra into the book now. That is the ninth yellow card of the evening so far and Juve's sixth.

They nearly have another as Bonucci reacts passionately to a push from Lewandowski.

That proves to be Ribery's last contribution, with the Frenchman now replaced by Thiago. Many will be surprised that it has taken this long for Guardiola to call upon his compatriot.

A bit of Argentina-Brazil rivalry as Roberto Pereyra and Costa exchange a few angry words.

Lewandowski tries to make room for a shot that is blocked. Ribery then attempts to glide his way through the Juve defence but is crowded out by Buffon.

Muller draws the ire of Bonucci for nearly stepping on the veteran goalkeeper.

Buffon is called into action once more to repel Ribery's cross. You sense this might be a long 30 minutes for Juventus, who have lost their spark on the counter.

Costa is never a player to lack confidence and his ambitious long-range shot skids along the turf before being scooped up by Buffon.

Good link-up play from substitute Mandzukic, who sets up Lichtsteiner for a left-footed effort that is held by Neuer.

How Allegri must wish that he had not taken off the dangerous Morata now.

After two quick team talks from Guardiola and Massimiliano Allegri, the first period of extra-time is underway.

There were no goals between Atletico and PSV at this stage last night, with the La Liga outfit eventually progressing 8-7 from the spot.

A predictable finish to events at the Nou Camp, where Barcelona cruise through to the quarter-finals and keep their unbeaten streak very much alive courtesy of some memorable goals.

That is not an end to his blog however, as we are set for 30 more minutes and possibly even penalties between Bayern and Juventus.

Can the Italians bounce back from that late, late equaliser?

End of 90 minutes

Bayern Munich 2-2 Juventus (4-4 on aggregate)

Full-time

Barcelona 3-1 Arsenal (5-1 on aggregate)

Arsenal are out of the Champions League

With the clock ticking down towards injury time, Bayern level the tie. Vidal knocks the ball wide to Coman, whose cross is steered in by the head of Muller at the back post. So cruel on Juventus.

Goal: Bayern Munich 2-2 Juventus (Thomas Muller)

The 'MSN' goal triumvirate is complete. Gabriel initially does well to stop the run of Neymar, but Messi picks up the loose ball and effortlessly chips over Ospina and into the far corner. Another terrific finish.

Goal: Barcelona 3-1 Arsenal (Lionel Messi)

No way through for Walcott, who is released down the right channel but takes a poor touch and makes it easy for the committed Ter Stegen to save.

Lewandowski has struck the crossbar for Bayern, but he was offside anyway.

Giroud is the next player to be cautioned as he bounces the ball in frustration after being whistled for a hand-off to the face of Alba. Perhaps a bit of hangover from the first leg there.

Bayern are monopolising possession in search of that important equaliser against Juventus. The reigning Italian champions are standing firm for now, though.

Arsenal provide a textbook lesson in how not to operate a zonal marking system. Four stationary red shirts stand and stare as Busquets sends a free header from Neymar's corner wide. That should have been another goal.

A decent double save from Ter Stegen to keep out both Sanchez's free-kick and Giroud's rebound drive.

Walcott then heads off target and Giroud crashes a volley into Sanchez and wide. Arsenal searching hard for an equaliser, despite their aggregate deficit.

Warm applause for Rakitic as he goes off and Turan takes his place. The latter wastes no time in getting involved, tripping Monreal to earn a deserved caution.

Game very much on at the Allianz Arena. The ball is fed wide to substitute Coman, who does well to ride the challenge of Evra before pulling it back for Costa.

The 25-year-old then picks out Lewandowski with a sublime left-footed cross and the prolific striker guides his header past Buffon from close range. 15 minutes plus stoppage time for Bayern to find another goal that will force extra-time.

Goal: Bayern Munich 1-2 Juventus (Robert Lewandowski)

A delightful piece of control from Neymar. The ludicrously gifted Brazilian then tries to set up Messi but Arsenal survive.

Plenty of substitutions now, with Roberto on for Iniesta. Messi will take over as captain. For Arsenal, a new attacking duo in Walcott and Giroud. Iwobi and Welbeck off.

The visitors look to respond immediately through Welbeck, whose shot clips the crossbar on its way over.

Sturaro replaces Khedira in Munich.

Any lingering hopes of an unlikely Arsenal comeback are doused in pretty sensational fashion. A typically sweet Barcelona passing move ends with Alves hanging a cross towards an unmarked Suarez and the former Liverpool favourite watches it all the way before twisting his body to volley into the top corner.

Superb technique and execution.

Goal: Barcelona 2-1 Arsenal (Luis Suarez)

Bellerin, Iwobi and Sanchez exchange passes before Busquets' block wins Arsenal another corner.

Welbeck loses his marker but cannot sneak a header inside the post. Offside flag raised against Sanchez.

Almost a decisive third goal for Juventus and it's Morata again as he bulldozes his way through the Bayern backline before his shot is turned over.

A second change from Guardiola sees Coman replace Alonso.

Barcelona have been woken up by that sumptuous Elneny goal. Messi and Neymar combine beautifully on the edge of the box, with a clever backheel setting the former up for a shot that is well saved by Ospina.

A poor defensive header from Mathieu then plays in Welbeck but the England striker lacks finesse and last man Mascherano makes a lunging block.

It is raining yellow cards in Munich. Referee Jonas Eriksson is evidently keen to keep control of proceedings and Bonucci is the latest player to feel his wrath.

Finally Arsenal have a reward for their efforts and it is a wonderful, bending right-footed strike from Elneny that beats Ter Stegen all ends up after positive work from Sanchez. That is the Egyptian's first goal for his new club since a £5m switch from FC Basel in January.

A glimmer of hope for the Gunners? A second goal in quick succession would certainly make things interesting.

Goal: Barcelona 1-1 Arsenal (Mohamed Elneny)

Alert defending from Alves to divert Iwobi's shot into the side netting. Sanchez is then cautioned for hauling down Neymar in midfield.

Tempers flare in Munich as Vidal reacts furiously following a 50-50 challenge with Cuadrado and is shown a yellow card for his troubles. Lichtsteiner is also booked for his role in the ensuing melee and Lewandowski is left in a crumpled heap after a strong challenge from behind by Leonardo Bonucci.

Guardiola has responded to that wretched first-half showing by replacing Benatia with Juan Bernat.

Both games are now back underway.

Not a bad first half by any means from Arsenal, but they have no goals or shots on target to show for it. There has been no shortage of eye-catching Barcelona football either and at present they are cruising through to the last eight.

Elsewhere, Bayern have it all to do if they are to avoid a last-16 exit. Guardiola's side have been defensively shoddy and deservedly trail having had their away goal advantage emphatically wiped out.

Half-time

Barcelona 1-0 Arsenal (3-0 on aggregate)

Bayern Munich 0-2 Juventus (2-4 on aggregate)

A potentially crucial save from Neuer as he denies Cuadrado a second with excellent reflexes at the back post. Bayern have been cut to ribbons at time during this first half, particularly down Alaba's side.

In Barcelona, Wenger is forced into an early change as Flamini is replaced by Coquelin. Another midfield injury blow?

Fine play from Bayern as Costa scoops a ball over the top for Muller, who does well to avoid the tackle before firing at Buffon. Patrice Evra's scrambled clearance strikes Lewandowski and runs out for a goal kick.

Arsenal are certainly creating chances now. Sanchez flashes a header inches wide of the far post after another dangerous Bellerin delivery and Welbeck plays a nifty one-two with Iwobi before shooting wide under pressure from Mascherano.

Morata joins Khedira in the referee's notebook for Juventus after an accidental high boot catches Kimmich square in the face. That had to hurt.

Iwobi involved again as he is picked out by Bellerin's cross and takes a couple of touches to evade Alves before blazing over.

Elneny is then denied by a fantastic block from Mathieu.

Iwobi wants a penalty after being sent through by Welbeck and having his heels clipped by Mascherano. Referee Sergei Karasev tells him to get to his feet before showing a yellow card to Gabriel for his overzealous protests.

A booking in each match as Flamini is cautioned for barging into the back of Andres Iniesta. Khedira, meanwhile, has his name taken for tying his shoelaces in the centre circle as Bayern attempt to restart the game.

That's a new one.

Juventus double their lead with perhaps the best example of a counter-attack you are ever likely to see. Morata is the architect, bursting forward after a Bayern move breaks down and committing multiple defenders with a skillful, slaloming run.

With the focus on him, he slides the ball over to Cuadrado and the Chelsea loanee stays calm, takes a touch to commit Philipp Lahm before rifling home.

Plenty of work to do for Bayern.

Goal: Bayern Munich 0-2 Juventus (Juan Cuadrado)

Flamini is the latest Arsenal midfielder to try his luck from range, only to see his effort fly over.

Buffon called into action for Juventus as he cuts out Ribery's back-post header that was set-up by a searching cross from Costa.

Terrific pressing from Juventus as Neuer's clearance is blocked by Khedira into the path of Morata. The Spaniard is clean through and looks to lob the goalkeeper, only to be flagged for offside.

The Bianconeri are giving a perfect demonstration of how to play Bayern at their own game here.

As if this tie was not over already, it certainly is now. Koscielny concedes possession in his own half and Barcelona quickly seize the initiative as Messi and Suarez combine to play in Neymar, who finishes coolly beyond Ospina.

Goal: Barcelona 1-0 Arsenal (Neymar)

Great vision from Neymar to find Messi, who ghosts in behind Koscielny and takes a glorious first touch before seeing a half-volley from close range turned over the crossbar wonderfully by Ospina.

From the resulting corner, Mathieu is left totally unmarked by Ozil but makes a poor connection with his free header.

Another long-distance shot from Arsenal as Mohamed Elneny drags one wide of Ter Stegen's right-hand post.

It is a very wet evening indeed in Barcelona, which means that many seats are empty.

Cool as you like from Ter Stegen as he shows his outfield qualities to take a touch and play a simple pass under pressure from Ozil.

At any other club, the manager would be going ballistic.

Arsenal have made a relatively confident start, but they almost concede after some fine interplay between Rakitic and Lionel Messi leads to a golden chance for Suarez. The visitors just about survive as the offside flag is belatedly raised.

At the other end, Ozil looks to test Ter Stegen but his powerful left-footed drive is wide.

The first goal of the evening comes from Germany, where Juve now lead 3-2 on aggregate. The usually reliable David Alaba fails to deal with Sami Khedira's lofted ball down the right channel towards Stephan Lichtsteiner and Pogba is left free to slot home with a low side-footed shot from the edge of the area.

Manuel Neuer came racing out of his goal to try and avert the danger, but his famous sweeper-keeper routine was found wanting there.

Goal: Bayern Munich 0-1 Juventus (Paul Pogba)

In Munich, Costa looks to tee up Vidal with an excellent low cross but the Chile midfielder, who won four consecutive Serie A titles with Juventus before a £28m move last summer, is unable to capitalise as his heavy touch allows Gigi Buffon to claim possession.

An early chance for Arsenal as Mathieu Ozil fools Mathieu and Jordi Alba with a cute no-look pass towards Welbeck, who gets his near-post shot wrong but it is blocked behind for a corner by Mascherano.

We are underway at the Nou Camp. Arsenal must end Barcelona's formidable 37-match unbeaten streak if their weakened side are to do the unthinkable and become the first team to overturn a 2-0 first-leg deficit in a Champions League knockout tie.

Bayern vs Juve is also off and running.

Just over five minutes remaining until kick-off in both of tonight's Champions League last-16 second-leg ties. Real Madrid, Wolfsburg, Benfica, Paris Saint-Germain, Manchester City and Atletico Madrid are the teams already through to the quarter-finals.

Gent, Roma, Zenit St Petersburg, Chelsea, Dynamo Kiev and PSV Eindhoven have all fallen.

Juve were struck by two major injury blows ahead of their trip to Bavaria after revealing that both Paulo Dybala and Claudio Marchisio had sustained calf issues during training.

Striker Mario Mandzukic was also rated as a fitness doubt, but he makes the bench as Alvaro Morata fulfills a lone front role. Giorgio Chiellini is still out with his own calf problem and Uruguayan international Martin Caceres will miss the rest of the season after tearing his achilles tendon against Genoa in early February.

In the evening's second tie, Arjen Robben misses out for Bayern having failed to recover from a bout of flu and Mehdi Benatia partners young Joshua Kimmich in the heart of defence with Holger Badstuber, Javi Martinez and Jerome Boateng still out.

Franck Ribery, Xabi Alonso and Thomas Muller retain their places after the 5-0 drubbing of Werder Bremen, but Thiago Alcantara, Mario Gotze and Juventus loanee Kingsley Coman all drop to the bench in favour of Arturo Vidal, Douglas Costa and Robert Lewandowski.

No messing around from Barcelona, who will be looking to complete the job tonight with a minimum of fuss. Jeremy Mathieu continues at centre-back in Pique's absence, while Marc-Andre ter Stegen, back-up to Claudio Bravo in La Liga, is back between the posts. Mascherano is in after that aforementioned suspension.

Dani Alves replaces Aleix Vidal having been left on the bench against Getafe and, as expected, Busquets and Rakitic are recalled to midfield in place of Turan and Sergi Roberto. Munir makes way for Suarez.

Former Arsenal skipper Thomas Vermaelen is a substitute, as is reported Premier League transfer target Bartra.

Koscielny returns at the expense of Per Mertesacker for Arsenal, who also restore Hector Bellerin at right-back ahead of Calum Chambers. Nacho Monreal starts instead of Kieran Gibbs, while Mathieu Flamini is preferred to Francis Coquelin and Danny Welbeck leads the line with Olivier Giroud listed among the substitutes.

Wenger's most intriguing selection involves Alex Iwobi. The 19-year-old academy graduate starts for the very first time in Europe having only ever been used as a substitute in the Premier League. He is in for Joel Campbell, who takes his place alongside Theo Walcott on the bench.

David Ospina continues to deputise for Cech in goal and there is no Arteta in the matchday squad, despite his recent return to fitness.

Juventus team to face Bayern Munich: Buffon, Lichtsteiner, Barzagli, Bonucci, Evra, Cuadrado, Khedira, Hernanes, Pogba, Alex Sandro, Morata

Subs: Neto, Rugani, Asamoah, Sturaro, Pereyra, Mandzukic, Zaza

We will have confirmation of the Juventus team as soon as it is released...

Bayern Munich team to face Juventus: Neuer, Alaba, Benatia, Lahm, Kimmich, Vidal, Alonso, Ribery, Costa, Muller, Lewandowski

Subs: Ulreich, Thiago, Rafinha, Bernat, Gotze, Rode, Coman

Arsenal team to face Barcelona: Ospina, Bellerin, Koscielny, Gabriel, Monreal, Elneny, Flamini, Iwobi, Ozil, Sanchez, Welbeck

Subs: Macey, Mertesacker, Gibbs, Coquelin, Campbell, Walcott, Giroud

Barcelona team to face Arsenal: Ter Stegen, Alves, Mascherano, Mathieu, Alba, Busquets, Rakitic, Iniesta, Messi, Suarez, Neymar

Subs: Bravo, Aleix Vidal, Bartra, Vermaelen, Sergi Roberto, Arda, Munir

Gerard Pique is unavailable for Barcelona after the yellow card he picked up during the first leg. Rafinha and Sandro are injured, while Jordi Masip, Douglas and Adriano failed to make Luis Enrique's 18-man squad.

Arda Turan is available after missing the first leg, along with Marc Bartra. Javier Mascherano will return after being suspended for the 6-0 thrashing of Getafe last weekend, while the likes of Sergio Busquets, Ivan Rakitic and Luis Suarez were rested.

Arsenal are expected to welcome back Laurent Koscielny tonight after the French centre-back sat out the last four matches with a calf injury.

Aaron Ramsey remains out with a thigh problem, however, while Petr Cech, Santi Cazorla, Alex Oxlade-Chamberlain, Jack Wilshere and Tomas Rosicky are also still sidelined.

Club captain Mikel Arteta is likely to be involved after returning to first-team training last week following ankle trouble sustained against Burnley in January.

Barcelona vs Arsenal is not the only Champions League last-16 second-leg decider taking place tonight, of course. There is also the small matter of events from the Allianz Arena, where Bayern Munich host Juventus.

The Bundesliga champions led 2-0 in Turin last month courtesy of away goals from Thomas Muller and Arjen Robben, yet frustrated outgoing boss Pep Guardiola by drawing the match after the second-half efforts of Paulo Dybala and substitute Stefano Sturaro.

You can also follow that fixture right here.

"A farce" was how Arsene Wenger described the sense of drama currently enveloping Arsenal earlier this week after they suffered a first FA Cup defeat in over three years courtesy of a rocket from Watford's Adlène Guedioura in a quarter-final tie at the Emirates Stadium.

Such a loss ended their hopes of lifting the famous old trophy for a third time in succession, while criticism of the manager's policies has only grown louder with the club having neglected to take advantage of their rivals' struggles to lie third in the Premier League and 11 points adrift of surprise leaders Leicester - not to mention six behind Tottenham - with only nine games left to play.

Although the Wenger moaning is certainly nothing new, it is unmistakably more widespread and vehement now and it is difficult to escape the feeling that the Frenchman's near 20-year reign is rapidly drawing to an unhappy close.

The Champions League has long been a source of pride and frustration for Arsenal in that time. Not since 1999 have they failed to progress through the initial group stage, although they have only gone on to reach the final once - in 2006, when late goals from Samuel Eto'o and Juliano Belletti condemned 10 men to a heartbreaking defeat against Barcelona at the Stade de France.

Europe's elite club competition is unlikely to prove a soothing tonic this season, either. The Gunners were somewhat fortunate just to make the last 16 following awful defeats to tournament minnows Dinamo Zagreb and Olympiacos and face a hugely difficult task in the Nou Camp tonight if they are to overturn a Lionel Messi-inspired 2-0 deficit and qualify for the quarter-finals.

IBTimes UK will bring you live coverage of that second-leg clash in Catalonia, with breaking team news, confirmed line-ups and updates to come shortly...
