PSG 1-0 Arsenal
Almost a swift second for PSG as Angel di Maria whips in a corner with real pace and David Ospina adjusts his feet really well to claw it out from right under the crossbar. Ricky Holmes scored one like that for Charlton the other week.

They have the tempo right now PSG. I'm not sure they will be able to keep it up but they are playing well. So far, Arsenal can't cope with the pace they are playing at.

Nick Bruzon: Celtic 1-0 down after 3 mins. Could be a messy night for them. Might we see the 7(seven) goal brackets?
Gabriel Paine: Awful defending from Mustafi. How did he let Cavani beat him to the ball so easily?
PSG 1-0 Arsenal
PSG are playing very, very well as they slice through Arsenal almost at will, Adrien Rabiot is the man bursting into the area but his shot is deflected over the top. Arsenal can't get near them.

PSG 1-0 Arsenal
A move of high quality from PSG. We make it 10 passes, some afterburners from Serge Aurier (19) and a classy glancing header.
Not bad in 42 seconds. We're not quite sure how they fitted it all in.

Marco Verratti goes into the book for a late and high tackle in midfield but Mesut Ozil wastes the free-kick. Is Arsenal defender Shkodran Mustafi struggling with a knock already? Rob Holding is warming up.

All of Celtic's work this week must have been on keeping Barca quiet for as long as possible. What now?

Arsenal are chasing shadows, and not particularly well. Time to see off the storm.
So Manchester City have had their match rained off and Arsenal and Celtic are both already losing. Top work.

What a great start. They really moved the ball around. Aurier one touch down the right, whips the ball in. It's a free header. What does Mustafi do? He points at the referee and says it's not a goal because there is another ball on the pitch. The ball is on the other side of the pitch. Cavani should be marked tight, he wasn't, 1-0.

Lionel Messi
Time to rip up that 'containment' gameplan as Lionel Messi scores with his first touch of the game.
I know it's easy to say from here but you would think that they might have kept an eye on the Barca number 10. He has all sorts of room on the left of the penalty area to thump a shot across goal and into the net.

Edinson Cavani
Wow! PSG take the lead after 40-odd seconds as they make a mockery of that chat about missing Zlatan Ibrahimovic.Arsenal's defence must have been watching Sunderland last night as they switch off and let Serge Aurier whip a cross in to the front post and Edinson Cavani buries a header!

Jonny Magrinho: Don't understand all the fuss about Arsenal's XI. Definitely good enough to beat a floundering PSG side without Zlatan.
LoveofFootball: Hmmm... Arsene for your sake I hope Ospina doesn't go all Bravo tonight. It's a weird looking line up but you are the manager.
