And Barcelona can breathe a massive sigh of relief. They were under a lot of pressure in that second half, with Real Sociedad pressing hard for an equaliser, but the home side did just enough to secure all three points, keeping them within touching distance of Real Madrid ahead of the Clasico.

- End of 2nd Half
FULL TIME: Barcelona 3-2 Real Sociedad
SUAREZ'S SHOT IS SAVED! Right at the very end the Barcelona striker gets on the end of a long ball, but Rulli comes off his line to make the save from Suarez and keep it at 3-2.
THAT WAS A WASTE! Real Sociedad worked the ball out to Yuri, who had time and space to drive into the penalty area, but he gets a little excited and blasts his shot well over.
Three minutes of stoppage time to be played at the end of the match.
Illarramendi has been excellent for Real Sociedad tonight, and this season in general. He's showing what Real Madrid saw in him all those years ago. He's controlled things here.
You don't often see this from Barcelona, especially at the Camp Nou. They are trying everything they can to run down the clock and make sure they secure the three points.
- Yellow cardGerard PiquéFC Barcelona
That's an easy decision for the referee, with Pique dragging back a Sociedad player. Yellow card warranted.
DENIS HITS THE TARGET! The Barcelona midfielder breaks forward and makes it to the edge of the penalty area before shooting, but his effort is straight at the Sociedad keeper.
Everyone associated with Barcelona knows that should Real Sociedad score an equaliser the title race would be as good as over, even with the Clasico coming up next week.
This has turned into a very tetchy affair at the Camp Nou. You could cut through the tension with a knife, with the Barcelona fans' nervousness making it down on to the pitch.
This Barcelona team looks really tired. It's worth remembering that this was the point of the season when they faltered last season as well. They just don't have the strength in depth.
That change has been made in the hope that Denis will give Barcelon a bit more control in the centre of the pitch. They need to show composure in midfield to see this game out.
- OffPaco AlcácerFC Barcelona
- OnDenis SuárezFC Barcelona
Here comes another change for Barcelona, with Alcacer coming off to be replaced by Denis.
Of course, the Clasico is looming. Barcelona and Real Madrid will clash next week. The Catalans need to be within touching distance of their rivals ahead of that match at the Bernabeu.
This could be Barcelona's season right here. April was always likely to be a defining month in the Spanish title race. Should Barca concede another here it would surely be over.
The introduction of Iniesta hasn't really changed anything for Barcelona. Real Sociedad are still the team on top, with the home team's defenders flustered by their high pressing.
There's a real uneasiness inside the Camp Nou now. The home fans are restless. They recognise that Barcelona are hanging on a little bit at the moment. Equaliser is coming.
Pique is distracted at the moment. He's arguing with the referee, opposition players, his own players... he needs to concentrate on keeping Real Sociedad at bay. They're pressing.
- Yellow cardLuis SuárezFC Barcelona
Suarez is shown a yellow card for throwing a yellow card into a Real Sociedad player. Warranted, but he doesn't think so.
- OffAndré GomesFC Barcelona
- OnAndrés IniestaFC Barcelona
There's the change from Lucho, with Iniesta finally replacing Gomes. That goes down well with the home fans.
Finally, here comes Iniesta. Barcelona need him to take a grip of this game because they have completely fallen out of it in the second half. They need to start moving forward again.
ACROSS THE FACE OF GOAL! Jose just couldn't stretch far enough to make contact with the ball. Barcelona are struggling badly in this second half. They look so vulnerable!
Ideally, Lucho would have liked to rest a number of key players for this match ahead of the Champions League second legs next week, like Atleti and Real did. But they just can't do that in their position.
ANOTHER SOCIEDAD CHANCE! Zurutuza gets away from Pique and squares a pass into the centre of the penalty area, but he had no support and the clearance is made by Barca.
The away team have made a change, but will Lucho switch things up soon? Barcelona need some fresh legs. He has sent Iniesta to warm up down the touchline. Surely he'll be on soon.
- OffCarlos VelaReal Sociedad
- OnSergio CanalesReal Sociedad
Real Sociedad make the first change of the match and Canales comes on to replace Vela.
This really isn't going Barcelona's way at the start of the second half. Real Sociedad have been well on top since the restart. It has to be partially down to weariness from the hosts.
BARCELONA SLEEPING! Jose found himself in acres of space, but he got the ball caught in his feet, allowing the home side to make a challenge. That was a big chance for La Real.
Of course, it's worth keeping in mind that Barcelona are still 3-2 to the good, but Real Sociedad are making a real go of this. Anything less than a win would be disastrous for the Catalans.
Real Sociedad have started the second half the better of the two teams, with Barcelona lethargic on the ball. Lucho might have to make a few changes here to re-energise his players.
Whistles ring round the Camp Nou for Gomes. The Portuguese international was eased off the ball by Illaramendi in the centre of the pitch and the home fans expect better from their players.
Martinez isn't happy with Suarez and squares up to the Barcelona striker. Indeed, Suarez appeared to trod on the Real Sociedad defender as he made a slide tackle.
This is really good pressing from Real Sociedad. They are pushing Barcelona high up the pitch, forcing their defenders and Ter Stegen into hurried clearances under a lot of pressure.
I just wonder if Barcelona's midweek Champions League exerts against Juventus might have an effect on the Catalans in this second half. Might they get weary as the half progresses?
There's just so much space in behind the Barcelona defence for Real Sociedad to exploit. There will be more goals before this game is out. Both teams look vulnerable.
The first half was a manic affair and the second half has also kicked off at a frenetic tempo. Both of these teams are looking to attack whenever they get the ball. Compelling.
That was an opportunity for Messi, but he could only send his freekick straight at Rulli. There was a lot of power on the effort, but it was straight at the Real Sociedad goalkeeper.
- Yellow cardAsier IllarramendiReal Sociedad
There's a yellow card for Illarramendi, and he can have no complaints. He brought down Messi cynically.
Rulli just about gets away with one. The Real Sociedad goalkeeper came way off his line, but slipped at the vital moment. He manages to scramble the ball away on the slide.
The second half is under way at Camp Nou! Barcelona have a 3-2 lead over Real Sociedad.

- End of 1st Half
HALF TIME: Barcelona 3-1 Real Sociedad. As is so often the case, Messi has been the difference between the two teams in this first half. Real Sociedad just can't live with him in this form. However, Barca have problems at the back.
- GoalXavier PrietoReal Sociedad
GOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOAL! Barcelona 3 Real Sociedad 2 (45 mins - Xabi Prieto). It's just so easy for Real Sociedad to create chances against this Barcelona defence. This time Prieto ghosts in between two defenders and side foots a finish past Ter Stegen.
- GoalPaco AlcácerFC Barcelona
GOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOAL! Barcelona 3 (44 mins - Paco Alcacer) Real Sociedad 1. The home side restore their two goal lead almost instantly! Messi plays in Alcacer, who does really well to get the ball out of his feet and find the far corner of the net with a low finish.
- Own-goalSamuel UmtitiFC Barcelona
GOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOAL! Barcelona 2 Real Sociedad 1 (43 mins - Inigo Martinez). Barcelona's dream of a clean sheet is over! Martinez resuces a cross at the back post, wriggling past two tackles before hammering a shot into the net off Umtiti, who knew nothing about it.
- Yellow cardPaco AlcácerFC Barcelona
Alcacer talks himself into trouble and is shown a yellow card. Sociedad have a freekick at the byline, but it comes to nothing.
Lucho would love his team to notch a clean sheet this evening. They have managed just one shutout in their last seven outings. Barcelona tend to give up loads of chances no matter who they play.
It's a long way back for Real Sociedad from here. They have held their own for the most part, but Messi has been the difference between the two teams as the break comes into sight.
- GoalLionel MessiFC Barcelona
GOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOAL! Barcelona 2 (37 mins - Lionel Messi) Real Sociedad 0. The hosts have doubled their advantage! Rulli made an astonishing save from Suarez, but the rebound fell to Messi, who bundled the ball home from close range to make it 2-0.
Messi just couldn't find a teammate inside the six yard box. He got to the byline and attempted to find Suarez with a flick of the ball with the outside of his boot. Intercepted, though.
The home supporters inside the Camp Nou are willing on Gomes every time he receives the ball, but that also seems to be making the Portuguese international nervous. He's on edge.
Gomes' touch lets him down. It just hasn't happened for him this season. He got on the end of a cross into the area, but his touch was poor and then he targeted his shot well over the bar.
Zurutuza appears to have a problem. The Real Sociedad player seems to have picked up an injury, and the away team might have a decision to make on whether to replace him.
Roberto has been very impressive for Barcelona in this first half. He has probably been their most effective attacking outlet, getting up and down the right wing, getting in behind La Real.
That was unfortunate. Real Sociedad had put together a good passing move, moving the ball into the Barcelona box, but Yuri lost his footing just as he was about to make the cross.
Real Sociedad are now attempting to play the ball around their midfield and defence, hoping to stem the flow of Barcelona pressure that has come their way over the last 10 minutes.
FLUFFED LINES! Oh dear. Roberto got down the right wing and played an excellent cross into the penalty area, but the unmarked Alcacer gets it all wrong and misses the ball.
Unlike both Atletico Madrid and Real Madrid, who fielded second string teams today, Barcelona can't afford to rest any of their key players for next week's Champions League second legs.
Ter Stegen has to make the save from Yuri. The Real Sociedad player took aim from the edge of the Barcelona penalty area, but a deflection from Roberto took the sting off it.
Having said that, Vela looks somewhat distracted at the moment. He's getting into arguments with Barcelona players. Not focussed. Keep in mind he's already been booked.
While Barcelona are on top at the moment and deserve their lead, Real Sociedad are still showing attacking intent and are making progress on the counter attack. They look dangerous.
It was actually good play from Alcacer that set up Messi for the chance from which he scored the opener. The former Valencia striker is starting to make an impression at Barca.
BIG BARCELONA CHANCE! Suarez gets to the byline, waits, and squares a pass right across the face of goal, but Rulli does just enough to put off Messi, who made no real contact.
When the ball was played to Messi the chance looked to be a bit too far out for him, but he got an incredible amount of power behind his strike to make sure Rulli had no chance.
Messi has been fairly quiet up until that moment, but the little Argentine has the quality to do that even when he isn't playing especially well. Barcelona needed that goal.
- GoalLionel MessiFC Barcelona
GOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOAL! Barcelona 1 (16 mins - Lionel Messi) Real Sociedad 0. Barcelona have the opener! What a sensational strike from Messi, with the number 10 finding the bottom corner of the net with a low drive from the best part of 30 yards out.
And so Gomes has been handed the place in the starting lineup that Iniesta would usually command. The Portuguese still hasn't made much of an impression on this Barca team.
Iniesta has once again been left on the bench by Lucho. The Barcelona boss clearly doesn't think he has the fitness levels needed to play two games in the space of just a few days.
BIG SAVE FROM TER STEGEN! That's another let off for Barcelona. Oyarzabal takes aim and forces Ter Stegen into a save. Real Sociedad are having a lot of joy in the final third.
FANTASTIC FROM RULLI! That was huge from the Real Sociedad goalkeeper. First he smothered a shot from Alcacer, then he comes out to deny Roberto the chance to get in behind.
Barcelona have started this game well, but Lucho will be concerned with how Real Sociedad have already managed to expose them at the back. The visitors will get chances.
- Yellow cardCarlos VelaReal Sociedad
There's the first booking of the match and Vela is shown the yellow card for a foul on Alcacer.
Of course, Barcelona come into this match on the back of a 3-0 defeat to Juventus in the quarter finals of the Champions League during the week. What impact will their European exerts have on this display?
SUAREZ SLIPS! That looked likely to be the opening goal for Barcelona, with Alba getting in behind, but his cut back caught Suarez off guard and the striker slipped at the worst time.
The pressure is on Barcelona with Real Madrid scoring a late winner against Sporting Gijon earlier in the day. The gap between the two teams before kick off stood at six points.
That was very nearly a lightning start to the match by the visitors. They have already exposed just how vulnerable Barcelona can be at the back. That could have been 0-1 to La Real.
PIQUE MAKES THE BLOCK! That was almost an opening goal for Real Sociedad, with Pique having to make the block to deny Yuri from finding the back of the Barcelona net.
