I don't think anyone was expecting this and especially a hat-trick from Mbappé. Barca have crumbled tonight. Their only two defeats this year have come in two crucial cup ties against Sevilla and PSG.
87'
And Barca are falling apart. The ball is passed to Mbappé in the box and he curls it into the far corner. Easy.
HT: Barcelona 1-1 PSG. We go in at the break level with PSG slightly edging it on chances. Ter Stegen has been the star man for the hosts.

It looks like this match will be level at the break.

This game has sprung into life.

Kean takes a touch, turns and shoots but Ter Stegen parries it out for a corner.
36'
Griezmann has a shot from just inside the box that goes inches wide. So close.
35'
Ter Stegen makes a diving save to avoid it going 2-1 PSG. Kurzawa with the effort.
33'
It had to be him. It had to be. Verratti flicks him the ball over, he takes it past Lenglet and fires it in the top corner of the near post past Ter Stegen from close range.
Icardi knocks it by the keeper but Pedri clears. The Argentine looked like he was offside.
18'
I think there will only be one goal that separates these sides, if that.
14'
Griezmann is played through in the box but he hits a very weak shot at Navas. He should have done better.
14'
It was always going to be a tight game.
10'
Alba has a cross that goes over the bar. We'll put that down as a shot.

No more chances but Barcelona are looking to do some attacking.
5'
Gueye has a shot from outside the box that he fires wide.

PSG have started the better side.

And we're off.
Start of match
PRVW
Sorry about that folks. It appears there was a technical glitch that meant the commentary wasn't showing. It's working now.
PRVW
Samo44 hopes that Barcelona will win 2-1. If they do concede then there are away goals tonight so PSG would only need to win the home match 1-0 to go through.
PRVW
The teams are now out. It's a shame that there are no fans to watch.
PRVW
I wonder if we will get a 6-1 like the last time these sides met.
PRVW
The time has come. What are your predictions?
PRVW
The last time that Barca failed to make it past the last 16 was 2006-07. They will hope to continue that great record.
PRVW
PSG will be hoping to make the final again this season and perhaps win it.
PRVW
The last match here was that famous 6-1 victory from Barca. PSG have never won here.
PRVW
The big news is that Piqué starts for Barcelona tonight.
