Edinson Cavani
The floodgates are well and truly open. Maybe it wasn't such a good idea for Celtic to score so early.
The visitors are really buckling now as Neymar and Kylian Mbappe both go for the same high ball in the penalty area. It hits the shoulder of the Brazilian and falls for Edinson Cavani to rattle home from right in front of goal.

Former Celtic goalkeeper on BBC Sportsound
"It’s brilliant play by Neymar, one-twos around the edge of the box. He gets to almost the same angle as his first goal, and he hits it so quickly across the goalkeeper that I don’t think Craig Gordon had any chance.
"But again, it goes back to giving the ball away, they’ve got possession in front of Celtic’s box and they play that little combination play.
"Every single chance PSG have had in this game has come from Celtic giving the ball away in their own half. I know it's easy looking from up here, but they're professional players, they must realise that if they give the ball away in those situations, a team of this quality will hurt them."
Neymar
He's done it again. Neymar plays a smart one-two with Marco Verratti on the edge of the Celtic penalty area and slots a sweet strike into the same corner of the net. Nothing Craig Gordon could do about that one. A perfect finish.
That's seven goals for Neymar in six Champions League outings against Celtic - and counting...
Paris St-Germain 1-1 Celtic
Celtic get good numbers forward again and this time Olivier Ntcham flashes a shot wide from 25 yards or so.
Paris St-Germain 1-1 Celtic
Kylian Mbappe drifts behind the Celtic defence far too easily as he latches on to a long ball over the top from Dani Alves. The striker hits it first time as it drops over his shoulder and it flies over the top - not by much.

Mikael Lustig seemed to injure himself trying to retrieve a wayward Scott Brown pass. Nir Bitton looks to have slotted in at right back. Is that a first for him? He’s done pretty well this season at centre-back but playing full-back is another thing entirely - especially against Neymar!

It's wide open as Callum McGregor and Moussa Dembele combine well on the left, the former's cross is spilled by Alphonse Areola. Neither goalkeeper covering themselves in glory so far.
Paris St-Germain 1-1 Celtic
Uh-oh. Celtic will need to make an early defensive change as Mikael Lustig pulls up. Nir Bitton is the man coming on. The lanky midfielder has been filling in at centre half for most of the season, so it shouldn't be too much of a disruption.

"I thought Neymar beat Craig Gordon quite easily. It was quite a tight angle and I thought Craig might have got a foot to that ball or come out towards him and killed the space."
Neymar
Oh well, that didn't last long. Adrien Rabiot shrugs off Scott Brown and strides forward to release Neymar. The Brazilian is too quick for Mikael Lustig and arrows a low shot across Craig Gordon into the far corner.
Not the best footwork from the Scotland keeper....

Paris St-Germain 0-1 Celtic
Buoyed by that early goal, Celtic are popping the ball around very nicely. PSG look a bit stunned.

"What a magnificent goal, straight off the training pitch, similar to the goal they scored against Kilmarnock.
"I don’t know what Dani Alves was thinking - it was almost as if he wasn’t bothered, he didn’t look up, it went out for a corner and Celtic got their goal.
"Celtic are going about their business, pressing PSG higher up the pitch than they did at Parkhead, and it’s worked to a point. It gives them something to hang onto now."
Paris St-Germain 0-1 Celtic
What a start for Celtic! That's the first goal PSG have conceded in the tournament this season.
Moussa Dembele
A shocking pass from Dani Alves gifts Celtic a corner and the visitors take full advantage. Olivier Ntcham drills it in low and Moussa Dembele powers on to it first time, with his rising shot too hot for Alphonse Areola to handle.

Former Celtic striker on BBC Radio Scotland
"It’s going to be big a question of Tom in terms of how he does the dirty side of the game. If I'm being harsh, it was his runner that scored the winning goal against Bayern Munich.
"He needs a big performance – at this level, can he do the dirty stuff of the game as well as the good stuff that we all see and love when he gets on the ball, carries it and bring Celtic up the pitch?
"He’s going to have to do that as well, otherwise Moussa Dembele is going to be a lost figure up there like he was against Bayern Munich a lot of the time."
