Ooooh. The Parc des Princes thought they were going to see the net bulge there as Kylian Mbappe found himself in space on the edge of the area but his shot takes a deflection and sails wide.

Three changes for the home side as Saul Niguez, Stefan Savic and Rodrigo Riquelme come on for Samuel Lino, Axel Witsel and Nahuel Molina.

We'll have four minutes added on in Paris.

Is there to be another twist?

Oops, the cards are coming thick and fast as Bradley Beraldo is into the book for a silly challenge and Barcelona youngster Fermin Lopez also ends up getting his name in there for having a go at referee Anthony Taylor.

WOW!

Almost level in Madrid as teenager Jamie Bynoe-Gittens hits a cracker from about 25-yards that dips on to the top of the crossbar.

Borussia Dortmund are really pushing for an equaliser here.

Huge chance for Atletico Madrid to regain that two goal lead as Angel Correa runs through on goal but Mats Hummels uses all of his experience to put the striker off.

Well he's scored what could be the winning goal here but Andreas Christensen goes into the book for a foul and that means he will miss next week's second leg.

Barcelona have got basically everyone behind the ball in an attempt to defend this slim lead.

Ousmane Dembele chops onto his right and whips in, it's not really a cross or a shot and Kylian Mbappe flings himself at it but can't get there. I think he was offside anyway.

Feels like there's been hundreds of subs in this game.

Marco Reus and Salih Ozcan come on for Marcel Sabitzer and Emre Can.

More changes. One each.

Fermin Lopez comes on for Ilkay Gundogan for Barca and Fabian Ruiz is off for Goncalo Ramos.

Attacking change for the home side.

Barcelona have scored three goals in a Champions League knockout game away from home for the first time since April 2015.

That was also against Paris St-Germain.

Teenager Pau Cubarsi goes into the book. He's actually been excellent tonight.

Another Atletico Madrid change as Rodrigo De Paul makes way for Angel Correa.

Around 10 minutes plus added time remain of this fascinating match.

17 goals in the four Champions League quarter-finals so far.

How's that for entertainment?

Just as that goal went in, I was typing that Andreas Christensen and Ferran Torres had come on for Raphinha and Frenkie de Jong.

I didn't get chance to say that before Christensen had scored. Talk about making a difference.

Jose Gimenez is next in the book for a cynical foul to stop the Borussia Dortmund attack

Has Gregor Kobel just kept Borussia Dortmund in this tie? I think so.

Samuel Lino looks certain to make it 3-0 but Kobel springs across his goal to save at point blank range.

Brilliant stuff.
