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.
