Looks like Merih Demiral is OK. Well enough to carry on for a bit anyway. He's still not moving 100% comfortably, but he doesn't want to depart this now.

As it stands, Man Utd are bottom of the group.

It's too easy.

The fans are getting on their backs.

That was awful defending from Manchester United.

It is a simple overlap that went completely un-noticed.

Once Davide Zappacosta slides the ball across goal, the home side can only hope.

Now that is a penalty!

Romelu Lukaku ties the Malmo defence up in knots and is eventually brought down in the box.

Andrew: It's all too easy for any team that plays Manchester United. Our defence is Swiss cheese and we have no offensive threat. Ole has to go. He doesn't have a clue and is in over his head - even the players know it.

I don't need to remind you that Solskjaer's United have been here before in Europe. They trailed to a slick opponent at home in the game prior to this and won it.

But relying on comebacks is becoming an almighty burden on this admittedly talented team.

Sleeping. Absolutely sleeping.

McTominay switched off, it's a great run from Zappacosta who slides the ball in first time.

Atalanta have opened up United very comfortably.

Jorginho wants a penalty, referee Francois Letexie waves it away... the Chelsea midfielder seemed surprised to find himself bursting into the box and went down under a bit of pressure.

Have Atalanta got an injury here? Merih Demiral looks like he's moving very uncomfortably. They've had a shocker with defensive injuries of late. They may well have another.

Terry: Yes!! First ever Chelsea goal for Christensen. Get in, great start. How many goals and assists have been our defenders made this season? It's been ludicrous really!

Mason Mount and Ben Chilwell size up a free-kick before Mount whips it comfortably over the crossbar. Malmo can't get out of their own half.

Neat footwork from Romelu Lukaku and a clever cross too, but he's the one usually on the end of those. No let up from Chelsea.

Bruno Fernandes is given two chances to deliver the corner. He hits the first man with both crosses. Poor. He's so much better than that.

The home fans scream foul, but Merih Demiral just went shoulder to shoulder with Cristiano Ronaldo. It is a Man Utd corner, though.

Atalanta boss Gian Piero Gasperini was furious then.

He thought his side had got themselves into a decent position on the edge of the box and took the wrong option.

The Italians move the ball around very well.

Bruno Fernandes ball over the top almost finds the charging Cristiano Ronaldo, but the keeper is out to clear... but only as far as Marcus Rashford.

The forward goes for a lob from range to catch out Juan Musso, but he slices it badly. Would have been special had he pulled it off.

Chelsea are piling on the pressure. Timo Werner drives forward and the ball eventually finds Romelu Lukaku on the edge of the box, he drags his shot a touch but it pin-balls towards goal and Malmo stopper Johan Dahlin has to make a smart save.

The visiting fans are making plenty of noise. European away days really are ace.
