Three of the top four in La Liga are in action with Barcelona visiting Real Zaragoza in the opening match of the night.

There's the whistle, Barca go top for now after a comfortable win in the end.

Thiago sees Messi but finds Bojan instead, in on the left and he can add a third but his shot strikes a defender.

Jarosik clears as Messi got on to Mascherano's pass.

Three minutes added time.

Bojan handles as he tries to control the ball down the left wing.

Lopez puts in the free-kick and Valdes flaps but Abidal is there, along with a couple of Barca team-mates, and nothing like a Zaragoza shirt in sight.

Pique is booked for protecting his face with his hands as the ball was fired in from close range. Come on.

BARCELONA SUB: Mascherano on for Busquets.

Villa is sent in by a sweet Thaigo pass and he hits the outside of the post!

An animated Jose Aurelio Gay is rowing with officials on the touchline and will be lucky not to be sent off... Off he goes. Bye bye.

A frustrated Braulio trips Busquets after his touch lets him down.

Guardiola is furious as Villa goes too early when he would have been clean through on to Messi's ball.

Neither side have really got any passes together as the game peters out.

All a bit grindy in the middle of the park as Barca look content now to see out the win.

Sent in but Abidal heads away for a throw on the right. Better from the hosts.

Now Zaragoza have a corner in their best spell of pressure of the half.

Thiago commits a foul around 30 yards out, the awarding of the free-kick provoking ironic cheers.

Bojan immediately has a shot from range which flies well over, although Doblas was initially worried by it. Thiago comes on for Iniesta.

Zaragoza will make another change as Said Boutahar, the Dutch-born Morocco international, comes on for Lafita.

BARCA SUB: Bojan comes on for Pedro.
