Barcelona bring on Andres Iniesta to a great reception. Andre Gomes comes off. 

Luis Suarez gives David Concha an arm to the face and goes into the book. A red card would see him banned for El Clasico - alongside Neymar.

Barca are so ordinary at the back this season. Another Real Sociedad chance but Willian Jose can't quite stretch enough to turn a cross home.

Real Sociedad have a corner... but it's cleared. Marc-Andre ter Stegen tries to set up a counter-attack with a long ball up the field but Barca lose possession again.

La Real come forward again and Barca switch off defensively, but the move comes to nothing.

End to end.

Real Sociedad bring on Sergio Canales for Carlos Vela.

Willian Jose squanders a great chance for Real Sociedad. He's picked out in space at the edge of the box but he wants to cut inside and runs into two Barcelona defenders.

There's a real lack of movement from Barcelona at the moment. Keeper Marc-Andre ter Stegen looks for options and doesn't really have them.

And then they break - you expect them to do it at pace - but Luis Suarez looks around for somebody making a darting run and can't see anybody. The move breaks down.

Lionel Messi tries to play in Luis Suarez, but the Uruguayan is offside. It's still a lively game but not as mad as it was in the final five minutes of the first half.

Sergi Roberto plays a good early cross, which Lionel Messi tries to finish - but he can't really get proper contact onto it and the chance is gone.

Lionel Messi - chasing a hat-trick - has a go at goal from the free-kick, from out wide, but his powerful effort is held by Geronimo Rulli.

Asier Illarramendi pulls Lionel Messi's shorts and gets a booking.

Real Sociedad keeper Geronimo Rulli comes out of his box and slips. But luckily he recovers to get it away before Luis Suarez can take advantage.

An open start to the second half with both sides going on the attack. Barca keeper Marc-Andre ter Stegen plays himself into trouble and is lucky his blocked clearance goes out of play.

The second half is under way. More of the same please.

Prince Gyimah: If this is how Barca will play against Juventus then they'd better hand them the tie. 

Barca host Juve on Wednesday, needing to overturn a 3-0 first-leg deficit.

Shortly before this live page started, Atletico Madrid beat Osasuna 3-0 - although they missed two penalties late on - taking their missed penalty tally this season up to six (out of eight) in La Liga.

Yannick Carrasco scored twice - and missed the first penalty. Filipe Luis scored their third and Thomas Partey missed their second penalty.

Fabious: Barca won't win league - not because they are poor but because of Enrique's team selections against smaller teams 

I need a lie down.
