Good afternoon and welcome to Eurosport's LIVE coverage of the Spanish Liga fixture between Barcelona and Real Sociedad. We'll bring you all the action as it happens at Camp Nou. Kick off is at 17:30 GMT.

Barcelona go back to the top of La Liga with three points here, but this wasn't the greatest of performances from the Catalans. In truth, they were slightly fortunate to get the job done because on the balance of play Real Sociedad probably deserved a point from this. Messi's penalty proves to be the difference.

FULL TIME: Barcelona 1-0 Real Sociedad

GOAL RULED OUT! The VAR is used to rule out that goal. Ansu was offside when the pass was played by Messi and the final whistle blows moments later.

GOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOAL! Barcelona 2 (95 mins - Jordi Alba) Real Sociedad 0. There's the finishing touch on the win for the Catalans! Messi played the ball through to Ansu, he cuts back inside and plays the pass across goal for Alba and the Barcelona left back slams the finish into the back of the empty net! Excellent goal!

Is there one last chance left in this match for Real Sociedad? On the balance of this game as a whole they probably deserve a point, but time is rapidly running out for them!

Big tackle from Lenglet! Real Sociedad created a good chance through Monreal, but his cross to the near post was blocked by Lenglet to prevent Portu from turning the ball towards goal. That was crucial!

There will be five minutes of stoppage time played at the end of the match!

It has to be said that this is a slightly strange change with Firpo coming on for Braithwaite.

Busquets is the latest player to be shown a yellow card as we enter the final few minutes.

The stuffing has been knocked out of Real Sociedad since falling behind. They looked to be building something, but Barcelona now look to have the three points in the bag now.

Griezmann comes off and he is replaced by Ansu. A poor performance by the Frenchman.

Was that a penalty kick?! Now Monreal goes down inside the box after being pushed by Griezmann, but the referee shakes his head. That looked to be more of a penalty that the one Barca were awarded!

La Real make a change after the goal and Jose comes on for Isak.

GOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOAL! Barcelona 1 (82 mins - Lionel Messi pen) Real Sociead 0. Messi steps up to the 12-yard mark and finds the back of the net with a calm penalty kick! Barcelona have been let off the hook a little bit here. This goal has come just at the moment Real Sociedad looked to be pressing for a winner.

PENALTY KICK TO BARCELONA! Wow! The referee has decided that it was a handball by Le Normand and he points to the spot!

VAR check! The referee has come across to the VAR monitor on the touchline to take a look at a potential handball by Le Normand. Did that strike the shoulder of the Sociedad player? Looked like it.

Monreal on the break! Real Sociedad come flying forward and the ball is played into Monreal down the left channel, but the former Arsenal defender pulls his shot across goal and wide of the far post!
