Goalless at the interval at the Allianz Riviera.

The hosts think they've taken the lead as Real Sociedad lose possession on the edge of their own area - seconds after conceding the equaliser - and Karim Benzema finishes with aplomb.

However, the Frenchman was marginally offside when he received the ball and the goal is chalked off.

Amine Gouiri has been one of the standout performers of the first half in Nice.

The 22-year-old wriggles past a couple of Paris St-Germain defenders before getting his shot off, but it's an easy save for Keylor Navas.

I'll tell you how. Robin Le Normand beat Casemiro to the cross, producing a magnificent challenge to prevent the Brazilian from prodding the home side level.

Superb defending.

Joseba Zaldua brings down Vinicius Junior and Real have yet another free-kick in a promising position.

They fail to make the most of the initial delivery, but Luka Modric regains possession and sends in a teasing cross towards Casemiro, who fails to make proper contact with the ball.

How did he not score?

The home side are starting to turn the screw as we approach the final ten minutes of the first half.

Amine Gouri cuts inside and tries to find Kasper Dolberg on the edge of the six-yard area, but Marquinhos hacks the ball clear.

David Alaba's effort is on target but the wall does its job. The ball strikes Alexander Isak and flies out for a corner, which the visitors deal with comfortably.

Both teams appear to have taken their foot off the gas after a frantic opening in Nice.

There has been little in the way of goalmouth action since those early opportunities.

Luka Modric whips the ball in towards the edge of the six-yard box but the visitors clear the danger and launch a counter-attack of their own.

Melvin Bard races clear down the left and floats in a cross towards Pablo Rosario, who sends his header high over the crossbar.

The Nice midfielder should have done a lot better there.

Casemiro's shot is deflected out for a Real Madrid corner but Real Sociedad win a free-kick from a resulting delivery.

The home fans are getting frustrated.

Carlo Ancelotti's side are really struggling to break down the visitors.

Rodrygo finds Eduardo Camavinga down the right but Asier Illarramendi is on hand to dispossess the young France midfielder.

All signs are pointing to a trying evening for both Real and PSG, who face each other in the Champions League last 16 second leg on Wednesday.

Nice are giving as good as they get, while Real Sociedad have looked pretty comfortable since taking the lead from the penalty spot.

It remains goalless in France, but both sides have gone close in the opening quarter of an hour.

The game has settled down a tad in the last few minutes, though.

Real Sociedad have kept 15 clean sheets in La Liga this season - more than any other side in the division.
