Ash: Petr Cech isn’t the top class keeper he used to be. He needs to be replaced.
Andy: Does anyone keep the ball better than Mousa Dembele in world football?!?
Tottenham 1-0 Arsenal
Spurs are 15 minutes away from a big win. Can Arsenal find a way through?

That could be a big miss from Dele Alli, because Arsenal are very much still in this game at 1-0 down, and it only takes one chance. They've got players to make those chances, too.

And Erik Lamela almost has a second!
He's played through on goal and his shot is well saved by a sprawling Petr Cech...

Son Heung-min played in midweek, so he's probably feeling it a little bit, but it's another good shift from him and he's become a real fan favourite at Wembley this year. Erik Lamela is exactly the type of player Arsenal won't want to see.
Tottenham 1-0 Arsenal
And another huge chance for Spurs! Arsenal are caught out with the ball at the back once more, it's played forwards and Dele Alli is onside, the ball bounces hip high and he clips a shot just past the post...

People who say Spurs are a one man team don't know what they're talking about. Son, Eriksen, Dembele, Vertonghen are all excellent.

That shot was Son's last touch - he comes off and on comes Erik Lamela.
Petr Cech is almost caught out as he plays a pass out wide from inside his goalmouth and Dele Alli gets a boot to it, but can't quite gather it in.

Daniel: Mhkitaryan trial period has expired. This is the Mhkitaryan we know at Man Utd.
Michael: Mkhitaryan’s disappearing act in this second half is exactly why United got rid of him.
Jay: Folks need to lay off Mkhitaryan. It'll take some time to wean him off Mourinho's philosophy

Erik Lamela is coming on for Spurs - and that's horrible! Tottenham have a four-on-three break after a turnover in midfield but Son leans back and slams a shot high into the stands.

As soon as Jack Wilshere opened up his body there, you knew he was going to shoot at Hugo Lloris' right side, and the Frenchman has done very well to get across and deny him.

Alfred: Harry Kane must be a genetically modified footballer. He is out of this world!
Dan Bell: Arsenal slipping further behind the top clubs. Arsene Wenger will leave Arsenal In a worse state than when he joined.

That's how the Arsenal jigsaw is shaping up now, although Pierre-Emerick Aubameyang is not very wide when Arsenal have the ball. Pretty much two up front. It could give Spurs space to exploit but a headache to deal with too.
Shot on target! Arsenal's first as Jack Wilshere curls an effort in from 20 yards but Hugo Lloris is on to it.

It looks like Alexandre Lacazette is going to play more centrally, with Pierre-Emerick Aubameyang moving out wide. But I think that's okay, Aubameyang is a very dangerous forward and he'll be able to adapt.

Anon: Nothing sticking up front for Arsenal. Throw on Giroud to play off on this massive pitch...oh wait, hang on?
Gaz: Arsenal are missing Ramsey's industry and runs from deep

Ex-QPR striker on BBC Radio London at Wembley
When he's in full flight there aren't many better midfielders than Mousa Dembele - his ability to change direction at pace, with the ball at his feet, is quite unusual for a big guy.
Tottenham 1-0 Arsenal
More great play from Mousa Dembele as he cuts out a posisble Arsenal attack, pirouettes away from danger and eats up 30 yards of space down the left wing.
A huge cheer from the Spurs fans as Henrikh Mkhitaryan is withdrawn, also coming off is Mohamed Elneny as Arsene Wenger goes for it.
On are Alex Iwobi and Alexandre Lacazette.

Mike Crick: Spurs are one man team. Check the stats. Their league position is entirely dependent on Kane staying fit.
Thor Jensen: Arsenal show what they are at the moment: a fairly decent Europa League team. Nothing more.
Tottenham 1-0 Arsenal
Mousa Dembele is a wonderful player in my opinion. A tank in midfield.

Bayo: The star of this Tottenham show is Mousa Dembele. The way he runs that midfield is so amazing. Never loses the ball. And gives the Dele the freedom he needs to roam.
Mike: Dembele has been super awesome today, he has controlled the midfield, just like he did against United
