HOW?

Kai Havertz whips a ball in from the left. It comes all the way through to Cesar Azpilicueta.

He tees up Marcos Alonso but his first-time strike is cleared off the line by Eric Dier!

Cristian Romero shrugs Kai Havertz off the ball on the left and works it out nicely from the back with Emerson.

The best player on the pitch has scored it. It's actually Dele Alli who is supposed to be marking him. He lets Thiago Silva get the run on him. It's a brilliant header from Thiago Silva.

Dele Alli has to stay on him there.

Marcos Alonso gets in behind on the left and smashes one first time. It's well saved!

Jussi Nousiainen: Tuchel still searching the best attacking formation. Playing with a physical nro 9 brought the best out of Werner at Leipzig. Now there's one at Chelsea.

Back under way.

N'Golo Kante is coming on for Chelsea. Mason Mount is off.

Petrus Lemba: If Werner was in for Mount then Chelsea could be a goal up at least. Mount hasn't been effective in final third. It's frustrating. Thiago Silva been incredible to watch.

Tottenham haven't let Chelsea play out from the back, they have pressed together as a unit and been excellent.

I think Chelsea have done okay. Kovacic has been outstanding for them, but hasn't been able to get into the game because Ndombele is doing a really good job on him. Lukaku is pulling onto Eric Dier and I'd like to see him play against Romero. He needs more support. Havertz and Mason Mount need to to get close to him.

Messiah Kaeto: Dele looks like a different player to the one that Mourinho didn’t want to pick. He has a point to prove and he’s doing well.

There were plenty of legends at Tottenham to pay their respects to Jimmy Greaves.

Tottenham started on the front foot and were brilliant for the first 15 or 20 minutes. Chelsea slowly but surely grew into it and the biggest chance tell to Mason Mount, who slipped.

It has been a really entertaining 0-0. I don't usually say 0-0 games are entertaining now, but that has been really good and has flown by.

A high-pressing start by Tottenham but Chelsea proving difficult to breakdown.

An intriguing contest.

Nice. Dele Alli flicks it over to Giovani Lo Celso but his pass through to Son Heung-min isn't great.

He flaps his arms in frustration.

Lee: Been pleasantly surprised with how much we've taken the game to Chelsea today but I feel that when we have the ball, we're still a bit a unsure and slow. That will cost us.

Tanguy Ndombele has got something in his eye and he's had to call the physio on to squirt some eye drops in there.

Whatever it is isn't coming out. Pierre-Emile Hojbjerg comes across to try and wedge it out.

Harish Lakka: Tanguy Ndombele finally gets to start a game, and you can already see the difference. Skipp for Dele should happen soon. Ndombele should start EVERY game.

Not with that delivery. Thiago Silva tries to flick it on at the near post but it's too low. Dele Alli blocks it, it gets caught under his feet but Silva scoops it out for a goal kick in a scramble on the floor.
