Um. Actually maybe the comeback is on.
Paco Alcacer takes advantage of a rare La Liga start to fire Barca back into the driving seat.
Lionel Messi - who scored the first two goals - plays the ball through to the Spanish striker, who smashes home from the edge of the box.

Actually scrap that talk of a comeback.
And just like that, Real Sociedad are back in it. Marc-Andre ter Stegen parries Willian Jose's header. Inigo Martínez smashes the ball through Ter Stegen's legs, and it hits Samuel Umtiti's face and goes into the net.

Carlos Vela nutmegs Paco Alcacer. Alcacer fouls Vela. He goes into book town.
That's Lionel Messi's 498th goal for Barcelona. He's got another 52 minutes left today...
If Lionel Messi's opener was one of his best this season, this is one of his worst. Luis Suarez's shot is saved by Geronimo Rulli. The rebound comes to Messi, who fails to make proper contact and kicks the ball off his leg and it goes in.

Andre Gomes decides not to take on a shot himself when the ball lands to him at the edge of the box, instead pulling it back to Jordi Alba, who smashes the ball well over.
Real Sociedad's Willian Jose is feeling confident and has an effort from about 25 yards but it's held by Barca keeper Marc-Andre ter Stegen, who has been as busy as his opposite number.
(Not at all) Fun fact, I used to think opposite number meant like number 13 and 31, or 23 and 32 etc.
Real Sociedad are playing quite well but at the moment they're not getting their final passes right, and not taking chances when they come. They have a corner, which Carlos Vela wins. Marc-Andre ter Stegen flaps at it but Gerard Pique clears.
It should be 2-0 to Barcelona. Striker Paco Alcacer, who has only scored four goals since his summer move from Valencia, gets the ball stuck between his legs when attempting to finish Sergi Roberto's cross.
Real Sociedad's Yuri Berchiche has his third shot of the game, this one is deflected and saved by Marc-Andre ter Stegen. Xabi Prieto nutmegged Sergio Busquets in the build-up to that chance.
Real Sociedad's Mikel Oyarzabal cuts in from the right but he fails to get any curl onto his shot and it goes across goal and wide.
That's Lionel Messi's 497th goal for Barcelona, who have already started tweeting until the hashtag #messi500 in anticipation. Surely you wait for him to reach that landmark first?
Lionel Messi plays a great ball over the top to Luis Suarez. Suarez waits and waits for someone to get in the centre and when he crosses, there's Messi. Geronimo Rulli bravely denies his fellow Argentine, but the keeper is down injured now.
It's Lionel Messi's 44th goal of the season - and it's one of his best. Good play from Paco Alcacer on the left to find Luis Suarez. Suarez plays the ball across to Messi, 25 yards, from goal and the Argentine sends a rocket of a shot in the bottom right-hand corner.
Lionel Messi
Magnificent Messi.
Real Sociedad should probably be ahead as a cross comes right to Mikel Oyarzabal but his shot from the centre of the goal is well saved by Marc-Andre ter Stegen.
And Oyarzabal now forces the Barcelona keeper into another save from outside the box.
