Welcome to live coverage of Barcelona's away trip to Sporting in La Liga.

Coming up now: Racing Santander v Sevilla.

The home fans are ecstatic at the final whistle - a famous result against a great side. They deserve the point, particularly for their first-half performance.

Barca with the ball in the corner but they run out of time! The Blaugrana don't win for the first time in 17 games. Incidentally it is also only the second time they have conceded first in the last 28 matches.

Pique penalised for an elbow on keeper Cuellar. Looked harsh.

Messi wriggles past many players and earns a corner. All sorts of paper being chucked by the home fans.

Barca attacking - Bojan is on for Iniesta as they go for the win.

There will be five hectic minutes added on.

Mate Bilic - just on for Castro - slams it into the wall and it is hacked away.

Sloppy from Pique and Valdes just gets to the ball before Barral... the striker caught the keeper but it was accidental. Valdes gets in his face and is booked - free-kick to Sporting right on the edge of the box!

Botia sees Villa out of play with time ticking down. A few moments ago Pep Guardiola seemed to shove Bojan away on the touchline... perhaps he wanted him to warm up more quickly!

The game becoming fractured as Messi breaks down the right and slides a ball across the face of the six-yard box... Pedro arrives and should score but it is just wide on the slide!

Messi working towards the box, cleared by Sporting. Canella then counters after sloppy play by Mascherano... Pique clears the danger.

Anger in the stands as the ref denies them a free-kick - but Villa flicks to an opposition player from a promising position. When Barca nick it back and attack again, the striker's ball through is to the keeper.

Xavi's kick headed away and Carmelo counters down thr right. Barca dispossess him but waste the chance with a loose pass. Sastre booked for dissent.

So can Barca find a winner to go 10 points clear? Messi tacked inside the corner of the box and Cuellar cannot prevent a corner.

That has subdued the home crowd, but they will refind their voice as the final whistle approaches no doubt.

The Spain star does not celebrate the goal, as he began his career at Sporting and played here for four years (in both sides) before leaving for Zaragoza.

GOOOOOOOOOOOOOOOOOOOOOOOOOOL FOR EL BARCA!!! Messi to Villa and Cuellar is off his line, inviting the small striker to chip him brilliantly to equalise!

Time running out for Barca.

Canella on the attack for the hosts, defended by Barcelona. Pedro then underhits a backpass and Valdes has to be out quickly to slide and clear!
