Arsenal stunned their hosts going on up early on.

Abou Diaby offloaded his pass to Theo Walcott - he raced clear on the right and set Nicklaus Bendtner up to score at the second attempt - But Arsenals joy would be short lived.

The goal fired Barca up and they were on level terms within three minutes.

Messi seized on a loose ball by the edge of the area and lashed a shot through a crowd of defenders into the top corner.
