"The finishing from the PSG players has been fantastic, top notch. Yes, the runners are going down the left and Celtic can’t compete with those runners, but Cavani, on the volley, again across the goalkeeper – absolutely perfect. You couldn’t get a better finish."

Corentin Tolisso allows Celtic's supporters to breathe a little easier, as the Frenchman nudges Bayern Munich ahead against Anderlecht once more, and as things stand, preserve Celtic's three-point advantage over the Belgian champions.

More consternation in the Celtic defence as PSG probe for a fifth goal. This time it's Kylian Mbappe with time to turn and shoot but the connection is weak and Craig Gordon flops down to make the save.

Hat-trick for Neymar? The Brazilian weaves his way past a couple of last-ditch lunges as Kylian Mbappe threads a pass through the legs of Dedryck Boyata but Kieran Tierney manages to get a foot in just before the Brazilian pulls the trigger.

PSG may not have been as clinical in the second half but some of their play is a joy to watch. Dani Alves continues to set the standard for attacking full-backs and Adrien Rabiot is such a graceful player. He has the makings of one of the best midfielders in the world for many years to come.

Kouassie Eboue gets his first taste of the Champions League as a replacement for Olivier Ntcham. It seems like a very long time ago now that the Frenchman set up the opening goal with Celtic's first touch of the ball.

The home side make a change but there's no rest for any the superstar attacking trio yet as Germany's Julian Draxler is replaced by Argentina midfielder Javier Pastore.

Celtic are caught with players up the pitch and suddenly the classy Adrien Rabiot is gliding forward to release Kylian Mbappe on the right. If the striker can pick out Neymar with a square pass it's a goal, but no, there's too much fizz on the ball for the Brazilian to connect.

There will be some very nervous Celtic fans right about now - Sofiane Hanni has levelled things up for the Belgian champions against Bayern Munich. As things stand, they will pick up their first point of the group stage, and sit two behind Celtic ahead of their showdown in Glasgow.

Now goalkeeper Craig Gordon is joining in with the poor passing as his effort is partially blocked by Dani Alves and falls to Edinson Cavani. The Uruguayan goes for glory from a very tight angle rather than picking out Kylian Mbappe in front of goal with a simple pass.

Not a lot of love for the Celtic defence out there...

Paul Thorburn:#Celtic, external getting an absolute doing here. As good as #PSG, external are the defending is so poor!

Andru Blakk: Think what annoys me is how easy their goals were. 3 of them were completely avoidable.

David Rose: PSG light years ahead but Celtic back four having a shocker.

"I really would hate to think it’s fear, but Boyata and Bitton delay things in the box, then Boyata just passes the ball away in midfield, and Cavani has all the space to control, turn and volley over the crossbar. I hope it’s not fear."

A sloppy pass out from the back by Dedryck Boyata is pounced upon and Edinson Cavani is presented with a shooting opportunity, with his effort dipping over the top.

Celtic captain Scott Brown takes a break from scrapping in the engine room to pop up on the right flank and he delivers a delicious curling pass for Moussa Dembele to race on to. The striker, under pressure from two defenders, shifts it on to his weaker left foot and can only slash a shot wide.

"That Lewandowski goal is a big relief for Celtic. They’re almost, talking about parking the bus, going with a back-five, with four in front of them and Dembele up front.

"They’re not really pressing the ball at all high up the pitch, so they’re hoping to get out of this one without any more goals conceded."

David Garland: What do you expect? PSG spent 220 million on one player.

Steve Bennett: Craig Gordon is past it, they need a top class keeper in the transfer window for the Europa League!

Graham Watt: Looks like it could end up 7 or 8 here after a good start as well.

The other bonus for Celtic is that PSG appear to be playing well within themselves at the moment. The tempo has dipped considerably.
