Barcelona thrash Celtic 7-0 in the other CL game
Messi scores hat-trick & Suarez nets two
Man City v Borussia on Wednesday at 19:45 BST
Tuesday's game at Etihad postponed because of adverse weather
Luis Suarez
Brendan Rodgers' mate gets on the scoresheet as Luis Suarez makes it six.
He has so much time and space, it would be embarrassing really but the gulf in class is titanic. Yet another assist for Neymar as he lifts a pass unchallenged over the Celtic defence, who try and play offside and fail. Suarez kills the ball high on his chest and lashes a volley into the roof of the net.

Apparently it's 'batter week' on Great British Bake Off. Looks like Celtic and Arsenal are taking part one night early.

PSG 1-0 Arsenal
Arsenal have to change this if they have any ambitions of leaving with a positive result. Arsene Wenger does change it, on comes Granit Xhaka for Francis Coquelin. He has one change left.
PSG 1-0 Arsenal
More circus defending from Arsenal as David Ospina duffs a pass out wide and plays it straight to Angel di Maria, he gets the ball back, lifts it over the last defender and then shoots. Good save from Ospina.

Chris Waddle
Former England winger in Paris for 5 live Sport
It was so easy for Paris to get through this team. Cavani has to lift it over the keeper to score, he should have four goals tonight.

This will make a good GIF! PSG run through the Arsenal back line and test David Ospina despite no player ever having the ball under control.
Adrien Rabiot runs through two men, the ball ping pongs around, comes off the back of Shkodran Mustafi and into the path of Edinson Cavani, he takes a bad touch and then shoot against the keeper's shins.

PSG 1-0 Arsenal
Jeers and whistles as PSG choose to turn and play the ball all the way back to the goalkeeper.This game is in danger of petering out.
But here's a chance, right-back Serge Aurier popping up at the end of a lovely flowing move but he can't lift the shot and it's an easy save for David Ospina.

That is Lionel Messi's 40th career hat-trick.Does he even bother collecting the matchball these days? His garage must look like a ball pool.

Lionel Messi HAT-TRICK
Make it stop, someone make it stop!
Barcelona are tearing Celtic apart at will as Luis Suarez drives into the penalty area, cuts it back and Neymar and Lionel Messi are both unmarked six yards out.
Messi beats his team-mate to the punch and slides it in. Hat-trick.
Image source, ReutersAndres Iniesta
Not a bad sub is he, Andres Iniesta?! What a goal this is, shades of Paul Scholes about it as Neymar gets another assist with a cross from the left and Iniesta arrives on it with a gorgeous, crashing volley from 15 yards out.
A belter!

Arsenal haven't had a shot on target yet. Mind you PSG have only had one.
Edinson Cavani scored with that header after 42 seconds, he's missed two other sitters. That's the game in a nutshell.

Bishop Yinkus: Make changes now Arsene, you are so headstrong old man, change Iwobi and Ox for Giroud and Xhaka.
Peter: Financially Arsene has done exceptionally well for Arsenal, considering watching them is the biggest waste of money in football.

Jonjo Shelvey grabbed the third with a brilliant 25-yard curling effort that beat keeper Alex Smithies.

A lot of comment on social media before the match about the bizarre Arsenal team selection. Views ranged from absurd through to delusional ....and that was on the positive side. It seems that the tactical leviathan, Arsene, is going all-out to disprove the premise that managers select their best teams for their toughest matches.

PSG 1-0 Arsenal
PSG have got in behind the Arsenal back line on countless occasions tonight and this time a clip over the top frees Angel di Maria in on goal.
He takes a touch, almost waits for Nacho Monreal to engage him and then goes down.
No penalty. Poor play, he could have easily got a shot away there.
