Harry Kane header sees Tottenham beat Arsenal in north London derby

Well that brings an end to our coverage from Wembley. Tottenham go third in the Premier League while Arsenal's demise continues.

We'll be back tomorrow with more coverage from the Premier League but until then, goodbye.

Full-time: Tottenham 1-0 Arsenal

Mesut Ozil's effort hits the wall and the whistle goes. Victory for Spurs given to them by Harry Kane's firm header. They had plenty of chance to make it a handsome win but as they failed to do that Alexandre Lacazette had two chances to get a point, both of which he wasted.

Mesut Ozil over it. This is the match.

Free-kick for Arsenal, 25 yards out from goal......

Four added minutes by the way, and we're into the last of those.

So close! Lacazette goes clean through in behind Sanches but he slides wide. That was a terrific chance, the best of the game, and it should be 1-1.

Now a Aubameyang cross goes out on the full. Arsenal really have been woeful, particularly in this second half.

And they nearly do.

Bellerin cross from the right and Lacazette peels back and hits a volley miles over the bar. What a chance.

Spurs are hemmed in. Can Arsenal get an equaliser?

Erik Lamela thrashes across goal and wide from a tight angle when he had Eriksen busting a gut to get into the area.

But will Tottenham be made to pay?

Just about sums it up.

Kieran Trippier heads it clear but Arsenal come again.

However, Welbeck can't rein it in and Spurs survive.

Now Danny Welbeck coming for Arsenal, as Granit Xhaka makes way. Now a corner for the visitors.....

Victor Wanyama on for Tottenham, with Dele Alli coming off. Six minutes to go and Tottenham have a corner.

Arsenal having plenty of the ball but Hugo Lloris is yet to be really tested. That Jack Wilshere effort is the closest the visitors have got. Aubameyang and Lacazette have offered nothing.

Into the final 10 minutes at Wembley. Can Tottenham put this game to bed, or will Arsenal produce the sucker-punch?

Petr Cech keeping Tottenham out single-handedly here. Eriksen's cross finds Trippier on the half volley and the Arsenal 'keeper parries it out. Amazing.

Tottenham create another chance and it needs Cech to keep out Lamela from a tight angle. Arsenal cut to ribbons again but they remain within a goal.

Cech's footwork has again been all the place today and he almost presents the ball straight at Dele Alli's feet as he tried to find Mustafi.

Now Alli pokes wide when put clean through. Arsenal make problems for themselves.

Son Heung-Min skies one over the bar, which almost hits the Wembley arch. That is the South Korean's last contribution as he is replaced by Erik Lamela.

Best effort of the day for Arsenal with three quarters of the game gone. Jack Wilshere collects the ball on the edge of the Tottenham box and tests Lloris who keeps the ball out and prevents the corner.

Two changes for Arsenal, and they badly need it.

Alexandre Lacazette on for Henrikh Mkhiatryan, and Mohamed Elneny off with Alex Iwobi replacing him.

Harry Kane powers a header into the corner.

Petr Cech makes a fine save from Eriksen's free-kick which was destined for the top corner. Spurs have taken complete control of this game. Arsenal haven't got going at all.

Kane denied again on the volley, as Cech keeps him out from the edge of the box. The rebound evades Son and Alli. Arsenal in survival mode.

It should be two for Spurs. Trippier crosses from the right and Kane is all alone but he heads just wide. You were waiting for the net to bulge there.

GOAL! Tottenham 1-0 Arsenal (Harry Kane)

Classic from the England striker. Ben Davis crosses from the left and Kane rises highest and heads his seventh goals in as many league appearances against the Gunners.

Players back out at Wembley. Rain still falling, hopefully the goals will follow.

Half time: Tottenham 0-0 Arsenal

Christian Eriksen and Mesut Ozil are struggling to get into this game and it is showing. Neither side have genuinely threatened though it has been a decent contest all in all, with plenty of zip and verve about the game.

Better from Arsenal as they approach the Tottenham area, but Hector Bellerin lashes over the bar.

Arsenal has really gone off the boil since the opening quarter of an hour. Mkhitaryan hacks a cross over everyone on the left and it goes out of play, sort of summing up his side's problems. Tottenham comfortable.

Best chance of the game so far. Eriksen's fires over a cross and Harry Kane is almost slightly surprised by it and he can only direct his header over the crossbar. Big opportunity, in the context of the game.

Neither side able to assert control in the early minutes.

Son Heung-Min is causing all sorts of problems down the left but his end product hasn't quite been on the mark as yet. Tottenham having more of the ball at the moment but bar a Harry Kane header they're yet to test Cech.

This is a genuinely pulsating contest early on. Not many chance but both sides throwing players forward whenever they get the chance.

Tottenham cut Arsenal apart as Kane finds Alli on the left. The latter tries to repay the favour but Mustafi turns the ball behind, via the outstretched right-hand of Cech.

Real open start to this game early only. This should be a cracker.

Neither side have really established a firm footing in this game so far, but Arsenal have forced an early corner which Tottenham clear with ease.

Under way at Wembley.

Earlier in the season, Arsenal pressed high and disrupted the Tottenham rhythm at The Emirates. Expect much the same of Arsene Wenger's side this afternoon, even with Spurs on their 'home' patch.

Teams on their way out in north London.

Less than 10 minutes until kick-off, so it is prediction time.

Tottenham 2-1 Arsenal

Any questions?

BT Sport are broadcasting the game live in the UK this afternoon, with Martin Keown among the punditry team at Wembley.

The former Arsenal centre-back has gone with a black poller-neck, grey jacket combination. He look somewhere between a supply teacher and a Bond villain. Not the best of looks.

Plenty of eyes on Henrikh Mkhitaryan today, who used go missing - let alone left out altogether - from these sorts of games for Manchester United.

He has been speaking about the main differences between Jose Mourinho and Arsene Wenger's managerial style. Read all about what he has had to say here.

Warm-ups under way at Wembley.

Arsenal might not have the best recent record at Tottenham, but they are on a good run at Wembley where they have won the last nine in a row including the FA Cup final last May when they overcame Chelsea.

Birmingham City were the last team to beat the Gunners at the home of English football. What odds on that run continuing this afternoon?

Spurs and Arsenal both find themselves in the unfamiliar position of outside the Champions League places at the start of play. But with Chelsea suffering a deluge of problems both sides have the chance to close the gap, with Tottenham even able to go third ahead of Liverpool if they prevail.

Chelsea do not play until Monday when they host Stoke City, giving the rest of the league a chance to take advantage.

Landmark day for Nacho Monreal this afternoon. The Spaniard has posed an attacking threat of late. Can he repeat that today?

We're approaching around 40 minutes until kick-off so that gives you all enough time to read our feature article on today's game.

This fixture has often been billed as an opportunity for one two to claim bragging rights over the other, but such has been Tottenham and Arsenal's problems this season the game is far more important than that.

To read more, head in this direction.

Jan Vertonghen speaking to BBC Sport: "A lot of things have been going on over there [at Arsenal] and between the top teams in the Premier League and it now looks like a different team.

"Obviously it's not but they have signed two great players now, we have played against both of them before for their different clubs, yeah they are great players and they won their last game quite comfortably, but we are just looking forward to playing them."

Aaron Ramsey out with a groin injury this afternoon. Okey Doke has stronger leg muscles than the Welshman.

Cold afternoon in north London, but the atmosphere is building nicely.

As for Arsenal, the most interesting piece of team news for them bar the returnees is the continued marginalising of Alexandre Lacazette who is on the bench for the second game in a row since the arrival of Pierre-Emerick Aubameyang.

I can't imagine this was what the Frenchman envisaged when he arrived at The Emirates in the summer as the club's record signing.

Despite claiming he was fit to play, and having featured against Newport County in midweek Toby Alderweireld is held back for Juventus in mid-week. Lucas Moura is on the bench. Interesting team selection from Pochettino.

And now Arsenal. Cech, Monreal, Wilshere and Xhaka all in.

Tottenham are first. And they are indeed unchanged.

We'll wait for both teams to confirm what has been revealed below, but it appears as though Tottenham are unchanged from the draw at Liverpool.

The main changes come from Arsenal. Petr Cech and Nacho Monreal are back after going off with injuries against Everton, but Aaron Ramsey misses out. Jack Wilshere comes in as does Mohamed Elneny.

Teams confirmed early? BT Sport reporter Des Kelly appears to have let them slip.

I am covering the game from around the north west area of London - not at Wembley I'm afraid - so have inevitably run into a fair few Tottenham fans who are in good spirits ahead of this north London derby.

Hope has turned to expectation now for Spurs when they face-off with Arsenal. Last year's defeat The Emirates was their first in seven league meetings; a sign of the upper-hand Pochettino's men have had in recent seasons.

Some support from a former player for Arsenal ahead of kick-off. They may need it.

More fuel to the fire ahead of the team news being revealed.

Not long from the team news from Wembley - still feels strange saying that for a Premier League fixture - but how should both sides line up?

Tottenham could give a debut to Lucas Moura, but Toby Alderweireld is fit to make his full return from injury in the top flight. Harry Winks and Danny Rose could also feature.

Petr Cech, Danny Welbeck and Nacho Monreal are all returning from injury but may all miss out for Arsenal. Alexandre Lacazette is bidding for a recall.

Tottenham and Arsenal may not have had the domestic campaigns either side envisaged at the start of the term, but they can breathe new life into their respective seasons this afternoon with victory in the 195th north London derby at Wembley.

Though Spurs' European adventures have illuminated their campaign, in the Premier League they have flattered to deceive with a title challenge to back up two seasons of improvement having failed to materialise.

The Gunners meanwhile have encountered the same seasonal problems which has dogged the second half of Arsene Wenger's 21-year spell in charge. Henrikh Mkhitaryan and Pierre-Emerick Aubameyang may have gelled effectively on debut last weekend, but there remains much to do to turn around their fortunes.

Both sides return to continental competition in mid-week but expect them to throw everything at each other in this lunchtime kick-off.

All the build-up and team news on the way ahead of the 12:30pm kick-off.
