A second-half double from youngster Bojan Krkic helped Barcelona to their first league victory in four outings as they overcame a nervous spell to beat Valladolid 4-1 at the Nou Camp and move to within four points of La Liga leaders Real Madrid.

Barca headed into the match under heavy pressure after taking just one point from their previous three league games and losing to Valencia in the semi-finals of the Copa del Rey.

They looked edgy after Valladolid midfielder Jonathan Sesma cancelled out a Samuel Eto'o goal with a penalty on the half hour, but Andres Iniesta settled their nerves when he restored their lead at the start of the second half.

Krkic made it 3-1, clipping in from a tight angle just after the hour, and capped an outstanding display when he poked home from a yard after Eto'o had swerved round the keeper and slid a pass across the face of the goal.
