Uefa Champions League quarter-final: Paris Saint-Germain 1-3 Barcelona - FC Porto 3-1 Bayern Munich - as it happened

What an evening of Champions League football.

The brilliance of Luis Suarez gives Barcelona what should be an unassailable lead to take back to the Nou Camp on a night to forget in Paris for a half-fit David Luiz.

But the main story undoubtedly comes from Portgual's second city, where Porto pressed high and showed no fear to earn a two-goal victory over a Bayern Munich side who lacked direction and a sense of urgency.

The Bundesliga leaders were very poor indeed after the break and will have to work hard to overturn that deficit on their own turf in a week's time.

That is all we have time for tonight, join us again soon.

Full-time scores

Paris Saint-Germain 1-3 Barcelona

FC Porto 3-1 Bayern Munich

A chance for Barcelona as Messi, looking for his 400th Barcelona goal, bends in a free-kick that is dealt with by Sirigu.

Porto still holding firm in the dying seconds.

Panic amongst the Barcelona defence as Ezequiel Lavezzi appeals for a penalty after being felled by Adriano.

Nothing given, though, and Cavani's follow-up is blocked by a determined Mathieu.

A lifeline for PSG as Van der Wiel's goalbound effort is deflected past Ter Stegen by substitute Mathieu.

3-1 in both games. A refreshing tonic after last night's cagey affairs.

Goal: Paris Saint-Germain 1-3 Barcelona (Gregory Van der Wiel)

PSG's stellar home record in European competition is about to come to an abrupt end as Suarez notches his second and Barcelona's third.

The former Liverpool talisman plays a neat one-two with Mascherano, nutmegs Luiz for a second time before beating Sirigu with a fantastic strike into the top corner.

Masterful.

Goal: Paris Saint-Germain 0-3 Barcelona (Luis Suarez)

A similarly jinking run from Messi sees him ease past four struggling defenders before shooting wide of Sirigu's right-hand post. A third goal for the visitors really would put this tie beyond reach.

A great goal from Suarez as he nutmegs the helpless David Luiz and holds off the challenge of Maxwell to beat Sirigu and extend Barcelona's lead.

Cavani responds with a fierce effort that requires a strong save from Ter Stegen.

Goal: Paris Saint-Germain 0-2 Barcelona (Luis Suarez)

Porto extend their lead through captain Martinez after a long ball forward was badly misjudged by Boateng.

The Colombian shows good composure to round Neuer and squeeze the ball home from a difficult angle for his sixth goal in seven Champions League appearances this season.

Substitute Sebastian Rode tries to respond immediately but his shot is saved by Fabiano.

Goal: FC Porto 3-1 Bayern Munich (Jackson Martinez)

A golden chance for Porto as Neuer makes a superb save to deflect Casemiro's strike on to the bar.

A second shot on target in quick succession for PSG, this time Adrien Rabiot sees an attempt comfortably saved.

Worried looks from the Barcelona bench as Iniesta goes down once again following a collision with Pastore and grimaces in pain.

The stretcher is brought on and Xavi is preparing to enter the fray.

Javier Pastore signals PSG's intent with a low shot that bounces awkwardly in front of Ter Stegen. The German parries the ball away to safety.

The players are back out at both the Estadio do Dragao and the Parc des Princes. Second-half updates to follow.

Bayern have recovered after a truly shocking start, but Porto should not be too disheartened at having conceded that away goal.

PSG, meanwhile, have it all to do after a tame first-half in which their only real threat came on the counter attack.

Half-time scores

Paris Saint-Germain 0-1 Barcelona

FC Porto 2-1 Bayern Munich

Cabaye swings in a deep cross for Cavani, who sends an acrobatic effort wide but again is adjudged to have strayed offside.

The half-time whistles sound.

A moment to forget for David Luiz as he is robbed in possession by Suarez and can only watch on in horror as the Uruguayan bends a shot on goal. Sirigu saves, but looks to have injured himself in the process.

Meanwhile, Casemiro heads over for Porto.

Iniesta receiving treatment after a hefty challenge from Cabaye but it looks like he will be able to continue.

Another chance for Cavani, who meets a cross from the left but can only send his shot into the grateful arms of Ter Stegen.

Cavani left all alone to head wide from a free-kick but the linesman on the far side is flagging for offside.

Porto hit the bar after a floated cross-cum-shot from Alex Sandro proves difficult to handle for Neuer.

Bayern reduce the deficit and notch a crucial away goal.

Jerome Boateng evades the attentions of Real Madrid loanee Casemiro on the right-hand side before delivering a cross that misses everyone before arriving towards the back post where Thiago can finish on the stretch.

A nice moment for the Spaniard, who has been dogged by injury issues since leaving Barcelona.

Goal: FC Porto 2-1 Bayern Munich (Thiago Alcantara)

Neymar looking dangerous as he weaves through Yohan Cabaye, Gregory Van der Wiel and Marquinhos before seeing a tame shot easily saved at the near post.

Deadlock broken at the Parc des Princes and PSG can hardly say they were not warned.

Messi capitalises on a poor pass, drives at the heart of the defence in acres of space before laying a simple through-ball through to Neymar who easily finishes past Sirigu.

Things then go from bad to worse for the hosts as captain Thiago Silva limps off to be replaced by David Luiz.

Goal: Paris Saint-Germain 0-1 Barcelona (Neymar)

Lopetegui's side reaping the considerable benefits of a high pressing game, here.

A relatively quiet start by comparison in Paris, until Lionel Messi rattles the post after receiving a lofted pass from Luis Suarez.

Maxwell gave him far too much space to work in and almost paid the price with Marquinhos left stranded.

A dream start for Porto as Quaresma scores his second goal of the evening, racing through after dispossessing Dante before coolly slotting past Neuer.

Can Bayern respond? Guardiola will be seething.

Goal: FC Porto 2-0 Bayern Munich (Ricardo Quaresma)

Thomas Muller berates the referee after being accidentally clattered by Bruno Martins Indi, but there was never any chance that he was going to award another penalty for that.

Robert Lewandowski then spurns a golden opportunity to net the equaliser as his header from a Muller knockdown loops over the crossbar.

Incredible start in Portugal, where Porto take the lead inside three minutes from the penalty spot through Quaresma after Martinez had caught Xabi Alonso in possession before being brought down by Manuel Neuer.

The World Cup winning goalkeeper can count himself lucky to have only received a yellow card.

Goal: FC Porto 1-0 Bayern Munich (Ricardo Quaresma)

We are underway in both games.

Barcelona, curiously, are the only team of the four in action this evening who failed to win their last league encounter. They led Sevilla 2-0 in the first half at
Estadio Ramón Sánchez Pizjuán, yet ended up drawing 2-2.

PSG hammered Bastia 4-0, while Porto beat Rio Ave 3-1 and Bayern Munich continued their march to yet another domestic title with a 3-0 win over Eintracht Frankfurt at the Allianz Arena.

A rather daunting stat for Barcelona....

Porto, who have not reached the last four of the Champions League since winning the competition under Jose Mourinho in 2004, beat FC Basel 5-1 on aggregate to progress to the quarter-finals having previously finished top of Group H with 14 points.

Pep Guardiola's Bayern easily saw off the challenge of troubled Shakhtar after finishing seven points clear of Manchester City in Group E.

These two teams previously met in the 1987 European Cup final, with Porto triumphing 2-1 thanks to goals from Rabah Madjer and Brazilian striker Juary.

This is the third time that PSG have met Barcelona already this season, with the two heavyweights having been drawn against each other in Group F.

Lionel Messi and Neymar were both on target during the latter's last trip to the French capital although their efforts proved to be in vain as Blanc's side claimed a 3-2 victory.

Barcelona had more success in the return fixture, with Luis Suarez joining his fellow attackers on the scoresheet to secure a comfortable 3-1 win.

No Zlatan Ibrahimovic or Marco Verratti for PSG tonight, with both players serving a European suspension.

David Luiz is only fit enough for a place on the substitutes bench after a hamstring problem and veteran midfielder Thiago Motta misses out with a thigh injury.

Barcelona's starting line-up looks as formidable as ever, although it appears that Javier Mascherano has been preferred to Jeremy Mathieu alongside Gerard Pique in the heart of defence.

In Portugal, Porto boss Julen Lopetegui has opted to start Jackson Martinez after the prolific Colombian was deemed a doubt for tonight's game with a hamstring injury suffered in early March.

Cristian Tello, on loan from the Nou Camp, misses out and centre-back Ivan Marcano is suspended.

Bundesliga leaders Bayern Munich are going through something of an injury crisis at present, with Arjen Robben missing with an abdominal issue and fellow winger Franck Ribery having not featured since hurting his ankle in the 7-0 demolition of Shakhtar Donetsk.

David Alaba, Javi Martinez and Mehdi Benatia are all also out. Bastian Schweinsteiger is suffering from illness and will play no part at the Estadio do Dragao.

Good evening and welcome to IBTimes UK's coverage of tonight's Champions League quarter-final first-leg ties.
