Good evening and welcome to Eurosport's LIVE digital coverage of tonight's Champions League clash between FC Porto and Atletico Madrid. Team news to follow...

That's changed things! Lemar swings a ball in, Kondogbia gets a flick on and an unmarked Greizmann capitalises at the back post with a gift of a tap-in!

Atletico have their first corner of the half.

VAR have had a quick look and see nothing in it.

Evanilson jumps for a header but is taken out from underneath by Hermoso.

Taremi has another great chance to put the host's in front but can't convert from 15 yards out, as Oblak denies him with his feet!

Diaz is enjoying himself out on the left-hand side and has bags of confidence. He drives at Vrsaljko in an attempt to create an attack but is dispossessed.

Porto should be ahead. Carrasco loses the ball in his own penalty box and Otavio capitalises, plays a ball into Taremi who fires his shot over!

Porto look to apply pressure on Oblak's goal straight away but Kondogbia clears up for Atletico and puts the ball out for a throw-in.

We're underway for the second half, and what a big half it is!

It's goalless at the break but Porto have been the better side so far.

It's all level at the break.

One minute to be added at the end of the first half.

Grujic picks up a loose ball on the edge of the area and drives into the box with it, but his shot is straight at Oblak!

The corner is swung in and after coming off Lemar's head, flashes past Oblak's goal towards the back post and out for anther corner! Porto are knocking on the door!

Diaz has an effort from the centre of the penalty area but his shot is deflected out for a corner.

Atletico are struggling to get out their own half at the moment. Porto are really pushing for an opener.

Taremi has been booked after following up Diaz's effort and catching Llorente.

The ball is pulled back for Diaz who stabs a ball at goal, but Oblak produces a brillaint save to deny Porto a lead!

Pepe is there again to deny Atletico a clear path at goal. He intercepts Greizmann's pass that was heading towards the six-yard box.

Grujic has an effort from 25 yards out but he scuffs his shot and Oblak comfortably collects.

Wow! How have Atletico Madrid not taken the lead here? Carrasco does really well to beat two players as he drives toward the byline before pulling a cross back for Lemar who flicks it on to the arriving Greizmann at the back post, who has an open goal to aim at but can't quite connect!
