It's a really open game, last-ditch tackles at both ends. There are 25 minutes for Barcelona to win at Real Sociedad for the first time in almost 10 years. There are 25 minutes for La Real to beat Barca for the FIFTH home league meeting in a row.

Luis Suarez is through on goal, goes around the goalkeeper and taps home. But he's offside, the whistle went before his shot.

There's not much between the sides now. Barcelona have been much better than they were, but they aren't outplaying Real Sociedad at all.

Lionel Messi
It's totally against the run of play but Barcelona are level. Neymar skips past a defender or two on the left wing and crosses to Lionel Messi, who takes a touch around the penalty spot before smashing the ball home. Good goal - but not reflective of the game at all.

Has that goal acted as a wake-up call to Barcelona? Not at all. For the second time Jordi Alba, who almost came off injured earlier on, denies Carlos Vela.

It's almost 2-0 to Real Sociedad but Jordi Alba's last-ditch tackle denies Carlos Vela. Barca have looked as bad as I've ever seen them.
Javier Mascherano was booked for a foul moments after the goal by the way.

Willian Jose
Real Sociedad finally deservedly lead. It's an absolute defensive shambles from Barcelona.
Carlos Vela goes past Javier Mascherano, who should do much better. His shot is saved by Marc-Andre ter Stegen, but only as far as Willian Jose.
The Brazilian, who once had a loan spell at Real Madrid, heads towards goal from the edge of the box and Gerard Pique kicks the ball into his own net, possibly with his injured foot.
It's Willian Jose's goal though.

Barcelona have their first shot on target as Neymar fires in the 20-yard free-kick but Geronimo Rulli denies him with a good diving save. Better from the visitors.

A rare dribble by Neymar in this game results in a free-kick as he's pulled back. Barca pass the ball around for a while from the free-kick before winning a set-piece in a possible shooting location.

Denis Suarez's first act is to play a fairly weak backpass to Marc-Andre ter Stegen, which the Barcelona keeper clears just before he's closed down. A bright start to this first half too from Real Sociedad.

Real Sociedad 0-0 Barcelona
The second half is under way now.

Well, Barcelona do make a half-time change, but it's not one of their struggling defenders. Ivan Rakitic is replaced by Denis Suarez in midfielder. A bit of a surprise switch.
