Ajax v Chelsea - as it happened
FT: Ajax 0-1 Chelsea!!! It's all over in Amsterdam and Chelsea have won thanks to a Batshuayi goal four minutes from time after combining with Mount and Pulisic. Chelsea had edged a rather even game, but it looked like it would end 0-0 until Batshuayi's introduction changed the game. Big win for Chelsea here, thanks for joining us and see you again soon!
20 seconds after play resumes, the whistle goes!

He's done it!!! Batshuayi scores!!! Mount has the ball outside the box, he gives it to Pulisic on the far flank and the ex-Dortmund man squares it for Michy who hammers home from 7-8 yards with the help of the bar. Alonso did well to let that ball go for the Belgian.
Zouma steps on Ziyech's foot and is rightly carded.
Chelsea better overall in my opinion, but a draw is fair.
Pulisic!! Batshuayi involved again in the build up playing a one-two with the American and Pulisic pulls it wide.
Tomori is adamant there's a handball in there, but the ref gives nothing. It may brush Tagliafico's arm. Play continues though. ,

Ajax sub: Neres on for Promes.
Batshuayi!!! What have you done? Pulisic's shot is deflected by Tagliafico straight to the Belgian, who chests it 10 yards from goal and then blazes well over the bar! That was a glorious chance. He had to hit the target at least.

Three shots to one for the Dutchmen in the last 15 minutes. Both teams are having good spells of play. A draw is fair.
Promes is offside from Van de Beek's pass. Correct decision.
Off the post!!!! Edson Alvarez runs in and heads the corner at the near post towards goal he's denied by the far stick. So unlucky. Abraham lost his marker.

Corner for the away side.
Mount hits one from outside the box and Blind gets his body in the way.
Willian looks to have come off worse as he took a blow to the face. He looks a bit dazed, but is carrying on for now after drinking some water.
And Tadic did not get off scot free.
It's cleared and on the counter, Tadic cynically bumps into Willian. He sticks his foot and body out. Both are down injured as it was quite a coming together.
Corner for Ajax here!
Early free-kick here for Ajax. Well away from goal though.
Welcome back everybody!! We are back underway here! No changes.
HT: Ajax 0-0 Chelsea! No goals at the interval in a game of few chances and has been relatively even. Chelsea probably just edged it, but Ajax finished the half well.

Chelsea certainly got a lucky break there as they were caught sleeping.
Scrap that!!! It's offside. Promes' shoulder was slightly ahead of Zouma and the goal is chalked off. Back to 0-0.
Ajax score through Promes!!! Ajax take a throw in deep in Chelsea's half, he plays a one-two with Tadic and Ziyech then crosses for Promes to head home at the far post. VAR will check, but it looks clean.
