Sandro Ramirez found the net against former club Barcelona to help Malaga to a 2-0 win at La Rosaleda.
A first home victory in 11 attempts over the Catalan giants was secured thanks to a first-half strike from Ramirez and a late close-range finish from substitute Jony.
Barca created just a few chances across the 90 minutes and were made to play the final 24 minutes with 10 men following a red card for Neymar, compounding their misery on a day that they saw Real Madrid extend their lead by a further point at the top.

Michel: "Following the victory against Sporting we're doing well. The players have shown that they can do it, and from now on we'll play with much less pressure. There's nothing more recuperating and regenerating than victory. When you win, there is less fatigue. We have players at our disposal, we already made a few changes the other day. I'm certain that Wednesday's win will help us to be less tired, although we'll see that we'll run the same amount as we did against Sporting".
Luis Enrique: "I like what I see, but it doesn't mean anything because, at the moment, we have not won anything or lost anything. Everything is still to be confirmed with titles. We have to win the game tomorrow against Malaga because if we don't things get a lot tougher. We have to focus on what we can control - getting three points in Malaga. We will look at other things later. Of course games between direct rivals are vital, but everything right now is Malaga."
MALAGA SUBS: Boyko, Demichellis, Charles, Duda, Penaranda, Jony, Villaneuva
