Barcelona cruised past Malaga 3-0 to go back to the top of La Liga with goals from Gerard Pique, Pedro and Alexis.
Despite creating a number of chances, Barca were made to wait until the 40th minute before breaking the deadlock, with Pique slotting home from close range after Alexis had flicked the ball into his path.
Pedro doubled his side’s lead shortly after the break with a neat finish, before Alexis secured all three points, finishing at the far post with a close-range strike.
