Awful short free-kick from Toni Kroos and Real Sociedad can break from the edge of their own box. Alexander Sorloth looks to sweep it across the box for strike partner Alexander Isak, but it's deflected behind for a corner.

Marco Verratti and Lionel Messi trade a few passes and cause all sort of panic in Lens defence.

In the end, Verratti plays Messi into space on the left but the Argentine is crowded out as he takes his shot.

Pin-ball in the Real Madrid box!

Alexander Sorloth can only send a header into the air. He gets up to meet it again and then Alexander Isak looks to nod it in, but Eder Militao does just enough to put him off.

It breaks to Mikel Oyarzabal after an unconvcining Thibaut Courtois punch, but he fires into the side-netting.

Lionel Messi lofts a brilliant diagonal ball into the box for Juan Bernat as he races into the area on the left.

He tries to find Mauro Icardi with a first-time volley back across goal, but the ball is cut out.

Casemiro is getting a ticking off. Luka Modric goes over to speak to his team-mate but gets a look from him to say he's in control of the situation. He's on four yellow cards this season, with the Madrid derby next up...

PSG are finishing the half strong. Well, stronger than anything they had managed in the first 35 minutes.

Lionel Messi seeing more of the ball might have something to do with it, but Icardi has also looked threatening. Just five minutes of the first half remains.

Vinicius Junior runs at the Real Sociedad defence but just takes too heavy a touch and the hosts seize the chance to break down the other end.

It's cut back for Alexander Isak, but Eder Militao dives in to block his low strike. Lively!

This looked like another huge chance for Mauro Icardi.

Lionel Messi plays a wonderful ball in, and the headed attempt is wide. It wouldn't have counted anyway, as the flag was up for offside.

PSG finally have their first shot on goal. It's taken 37 minutes.

Mauro Icardi is found in the box by Achraf Hakimi, and the Argentine stings the palms of Jean-Louis Leca.

Casemiro thunders into a tackle on Alexander Isak and the home crowd erupts. Looked like the Real Madrid man got just enough of the ball to avoid a booking.

Lionel Messi and Mauro Icardi try force something for PSG.

Messi plays a pass to the feet of his fellow Argentine, who quickly tries to return the favour. Possession is lost in the process and the chance is gone.

Alexander Sorloth scurries after an underhit back pass but Thibaut Courtois just about beats him to it. Eder Militao and David Alaba have so far dealt with the Real Sociedad front two of Sorloth and Alexander Isak well.

Gael Kakuta should have done better with this one for Lens.

The ball is wonderfully cut back for him in the box. He has the time and space to kick his spot. In the end he side-foots a tame effort into the Navas' grasp. PSG are being totally outplayed.

Keylor Navas is again tested. This time is Ceick Doucoure who rifles in a volley. The keeper would have seen it late as it passed through a throng of bodies. Good save in the end.

Real Sociedad come forward for the first time in a while and Diego Rico's driven cross is almost turned in by a Real Madrid defender, but instead goes behind.

Was begging for a team-mate to get on the end of that one.

Angel Di María and Marco Verratti try to link up for PSG now, but a corner is all they muster for their efforts. PSG doing it hard.

An excellent long ball out of defence finds Arnaud Kalimuendo-Muinga free on the left for Lens.

He looks to be away for a one-on-one with the keeper, but the defence tracks back to puts pressure on. In the end Kalimuendo-Muinga takes his shot early and Navas saves easily.

Toni Kroos strikes it, but it's straight into the wall.

Igor Zubeldía has no choice but the bring down a flying Vinicius Junior right on the edge of the Real Sociedad box.

Toni Kroos fancies this one...

Jonathan Clauss lets rip with the free-kick.

It's a dipping effort that bounces dangerously in front of the keeper, but Keylor Navas does well to get down to his right to parry it away.
