Neat work from Real Madrid down the left and the ball is then whipped deep for Vinicius Junior. He nods it down smartly for Luka Modric, whose effort is blocked by a sea of retreating La Real defenders.

Danilo Pereira makes a clumsy challenge after PSG concede possession cheaply in their own half.

Lens have a free-kick in a dangerous area about 35 yards out.

Przemysław Frankowski links up with Seko Fofana on the left edge of the box for Lens.

Frankowski cuts the ball back and Fofana again tries his luck from distance. It's easily dealt with.

Lens have certainly had the better of the chances in the first 22 minutes.

Rodrygo gets his first chance to run directly at the Real Sociedad defence and unleashes a fierce strike from a narrow angle that Alex Remiro can only palm behind.

Real Madrid growing into this one.

Lionel Messi now goes for it himself.

There are three Lens defenders closing in around him, but he drifts in from the right and has a go from outside the box. His low shot, however, flashes past the near post.

Adnan Januzaj wriggles in off the right, plays a one-two with Alexander Isak and then strikes at goal from distance, but his effort squirms wide of the post.

Now the ball breaks kindly for Lionel Messi and he has space to run at.

You know danger is coming. He spots Angel Di Maria in the box and tries to chip the ball over the defence to find his fellow Argentine. Lens do well to clear.

Karim Benzema is kneeling on the pitch, captain's armband clutched in his hand.

The Real Madrid forward is going to have to come off with what appears to be a muscle problem - it looked like he was holding his hamstring.

Benzema is replaced by Luka Jovic.

Real Sociedad have had the better of the opening 15 minutes, without testing Thibaut Courtois in the Real Madrid goal. The visitors have looked dangerous on the break, too.

PSG are trying everything to build their attacks from deep.

The latest attempt is eventually played to the feet of Lionel Messi. The Argentine is a long way out, with his back to goal and can only turn into trouble.

And so he plays it backward, and they start again. The visitors are yet to have a shot after 15 minutes.

Lovely delivery from Diego Rico, curling it delicately towards Alexander Isak and the Real Sociedad forward looks poised just to flick it into the net - he gets a head to it, but Eder Militao is covering superbly and gets his boot to the goalbound ball.

Seko Fofana, who has got on the ball plenty in the first 10 minutes, has a crack from distance.

The shot is fierce, but is blocked by Danilo Pereira and goes out for a corner, which comes to nothing.

Jonathan Clauss sends Lens first attempt on goal well wide and high.

It opened up there on the right for Frenchman. Maybe he should have squared the ball. Instead he went for glory and it was a waste.

What a touch from Vinicius Junior, delightful technique as the Real Madrid forward takes it on the outside of his heel to knock it into his path before accelarting down the left.

The move comes to nothing, but he's looking like a player full of confidence.

Lionel Messi gets on the ball as PSG try to play it out from the back. Facundo Medina smother's the Argentine. He is a little to eager and gives away the free-kick.

PSG are yet to really get going in these fist eight minutes.

It's noisy in San Sebastian. A great atmosphere with the Reale Arena bathed in blue and white as the rain comes down.

Alexander Isak shifts it left to Diego Rico, but his cross is closed down.

Przemysław Frankowski found himself in some space with a bit of time to pick his cross for Lens on the left, but it's easily blocked. The hosts are looking bright.

La Real just about get away with playing it out from the back! Karim Benzema and co were hunting down goalkeeper Alex Remiro, who somehow managed to successfully side-step his way out of the six-yard box.

Oooh, Martín Zubimendi tries to slide a pass into the path of Alexander Isak, but Eder Militao steps out well to cut it out - the Real Sociedad forward was in if he didn't.

Real Madrid break quickly and Vinicius Junior gets an effort on target, although it's comfortable for Alex Remiro.

It has been all PSG in these early few minutes. Slow, patient exchanges of passes through defence.

They are very much just feeling their way into this game in front of a very loud crowd at Lens.
