Chelsea manager Thomas Tuchel goes for experience to ensure a result after the loss away to Juventus. He brings Antonio Rudiger and Thiago Silva back into defence, while Jorginho is back in midfield from the win at Brentford. Mason Mount is back as well as Chelsea put the big guns out to get the three points tonight.

Dynamo Kyiv are on a club record run of failing to score in four successive European games.

Their most recent European goal was by Vitaliy Buyalskyi in the Europa League against Club Bruges in February.

Noah Okafor has just fired Salzburg ahead against Wolfsburg.

Mykola Shaparenko hooks the free-kick in for Tomasz Kedziora but he's so far wide he can't do anything with his header.

Barcelona are looking fairly comfortable so far, Marc-Andre ter Stegen is yet to make a save.

He receives a backpass and plays it out - which gave him something to do at least.

Ansu Fati goes close to an unreal goal.

He closes the keeper down and the resulting loose ball goes to Memphis Depay, who pulls it back to Fati.

Fati flicks it up twice with his back to goal and hooks a shot wide without even looking.

Two of his team-mates suggest he could have passed it to them since they were facing the goal.

I have been wondering whether Manchester United manager Ole Gunnar Solskjaer was brave enough to make big decisions.

He has made a couple tonight.

Firstly, he has dropped Paul Pogba. Secondly, he has paired Scott McTominay and Fred in central midfield instead.

It is fair to say there are many pundits and United fans who do not feel that pair has what it takes.

Solskjaer has ignored them.

Barcelona look a bit more slick since bringing on two talented forwards. Memphis Depay finds Frenkie de Jong and he tries to lay it on a plate for Ansu Fati but it's booted behind.

Memphis Depay's corner is cleared.
