Great defending by Marquinhos as Kingsley Coman powers into the box from the left but the PSG man positions himself well to block the cross and the ball goes out from a corner. The ball is whipped in and Eric Maxim Choupo-Moting has a great chance at the far post but somehow fails to get a touch.

Porto - who are playing some tasty stuff - win their fourth corner as Ben Chilwell is forced to put behind.

They play the corner short and eventually concede a free-kick.

I just remembered Toni Martínez is on Porto's bench. It can be quite tricky to shoehorn mentions of Oxford United into Champions League knockout games. So let's hope he gets on.

Arjun Singh: So slow and ponderous from Chelsea tonight. Jorginho has been a liability so far.

ThrillsInManila: Playing Bayern Munich is horrendous!! These man are always attacking!!! Constant pressure!

Femi: Interesting team chosen by Tuchel. Jorginho already struggling and nothing going forward for Chelsea after the first few minutes.

Bayern are doing a better of job of cutting off potential PSG breaks from their own attacks. Kylian Mbappe tries to make something happen by himself with a solo run but in the end he is stopped by a Bayern player.

I'm told Chelsea's kit is 'ember glow and ultramarine' and not salmon and blue...

Porto have a series of corners and Edouard Mendy just punches one away before it goes straight in.

Thumb up if you think better to play home first. Thumb down if you prefer away first.

Otavio whips this free-kick in and it's headed behind by a man in salmon (?) and blue.

Big save by Keylor Navas as he reacts quickly to keep out a Leon Goretzka header from a free kick. Navas is called upon again soon after to keep out a Benjamin Pavard effort.

Porto are neat and tidy in midfield. That's why when people say Chelsea are favourites, well, yes they are, but Porto have got some really good technical players in there. They will cause Chelsea problems.

Three shots so far, all for Porto. But two of them were blocked. No saves needed yet. Porto have a free-kick on the left wing, hopefully it's better than their last one.

Manuel Neuer punches away Neymar's free kick as PSG threaten following a spell of Bayern pressure.

You can't take your eye off this game, feels like either side could score every time they attack.

This is probably a better game for the tacticians to watch than the football fan who just wants lots of action (me).

Since making his competition debut in the 2013-14 campaign, Neymar has assisted 25 goals in the Champions League, the most of any player in this time.

Kingsley Coman charges off down the left before whipping the ball into the box. It is put behind by a PSG player before Joshua Kimmich's corner is headed away.

Really good stuff from Porto. Sanusi the left-back always wants to get forward. They have some good technicians in this line-up. Both teams are trying to get forward, though. Neither side is sitting back in this one.

First Chelsea attack in a few minutes but Mason Mount's left-wing cross is plucked out of the air by Agustín Marchesín.

It's all Porto at the moment. A ball is played into Zaidu Sanusi (who is in my fantasy Champions League team) but he can't find a team-mate with an attempted volleyed cross.

PSG have the ball in the back of the net again as Kylian Mbappe races through. He gets into the box and finds Julian Draxler, who slams home but then the flag goes up with Mbappe having been offside.

Still, the visitors look so dangerous on the counter.
