That was such a goal mouth scramble! Eventually when it pops across the six yard box it looked like Cesc Fabregas had a tap in.

He almost got his foot stuck in the ground. That was agonizing for Antonio Conte.

Former Liverpool centre-back Sebastien Coates is scoring goals for Barcelona... but he's playing for Sporting Lisbon.

His own goal has broken the deadlock in Portugal as Barcelona now lead.

And Chelsea should be ahead! What a performance since the break from the visitors. Again Eden Hazard is the creator, digging out a low cross which Cesc Fabregas stabs wide on the stretch. So nearly a lead.

What a brilliant ball in from Eden Hazard and Morata did exceptionally well to steal half a yard on the defender.

That was a great move and you can see how much that meant to Chelsea. This is a tough group and you expect these two to be fighting it out for the top spot.

Victor Moses with a range-finder from 20 yards, it fizzes just past the post as Chelsea continue to push hard for an equaliser. Still more than half an hour to go.

Former Manchester United boss Louis van Gaal is in the crowd in Paris.

He's watching a cracker.

Thiago Silva is well placed to prevent Javi Martinez's header crossing the line before PSG surge forward.

It looks like 3-0 when Kylian Mbappe finds Neymar unmarked deep inside the Bayern penalty are but the Brazilian blazes a great chance wide.

That was a really good cross and Morata was just inches away from getting on the end of that.

Chelsea again, have started off strongly.

Superb ball in from Cesar Azpilicueta - just ahead of Alvaro Morata! Those two have already combined well at times this season.

Antoine Griezmann is booked for hauling down Eden Hazard.

Chelsea are certainly not out of this and I think they will create two or three good chances in this second-half.

Will they have the composure to tuck them away?

Hat-trick? Denied! Romelu Lukaku goes close again but his powerful shot is too close to Igor Akinfeev, who sticks out a big hand to push it clear.

Spotters' badge to Anthony Martial by the way. A terrific pass into his partner in crime's path.

Alvaro Morata is fouled out wide but the free-kick comes to nothing. Wasteful. At the other end Gary Cahill brings down Angel Correa and could have been booked. From the free-kick Saul heads wide.

First shot of the second half comes from CSKA's Aleksandr Golovin, it's a very neat passing move too from the army men, but Golovin's drive is narrowly over.

You can see when Diego Costa gets into that team he will give Atletico Madrid such a boost but Chelsea are doing fairly well away from home.

Danny Mills was right though. What a ridiculous foul from David Luiz to give away. It's ridiculous, unnecessary and annoying!

Away we go! Soon to be under way in all the night's other games too.

It's beautifully poised for Celtic but in a Champions League context it's second-rate stuff. Ntcham gave it away four times in the first 15 minutes, Sinclair gave it away, Rogic gave it away. It was an epidemic of misplaced passes. The good thing is that Anderlecht haven't been up to much. They don't look like cutting Celtic apart. Celtic's goal was a moment of beauty dropped into a load of rubbish.

A fair point Jon. It's the old 'if you give a penalty for that you'd give x amount a game' argument. But it's a clear penalty by David Luiz. He had a handful of the shirt of Lucaz Hernandez.
