Real Madrid secured their ninth straight win after coming from behind to beat Sporting Gijon 3-1 on Saturday to open up a three-point gap over rivals Barcelona.
The home side were the better team in the first half but lacked the killer touch in front of goal with Gonzalo Higuain missing two excellent chances.
After the break, Sporting went ahead against the run of play through David Barral. Just a minute later, Rafael Van der Vaart brought Real level, although replays suggest he controlled the ball with his hand, and then Xabi Alonso headed them into the lead.
Higuain finally got on the scoresheet to finish off the threat from Sporting.
A surprise 2-0 defeat for Deportivo La Coruna against Valladolid allowed Athletic Bilbao to move above them into a Europa League place. The visitors took the game to Deportivo from the start and Nauzet Aleman put Valladolid ahead six minutes before half time. Deportivo showed little guile or invention in the second half and in injury time Valladolid scored again on the counter-attack through Haris Medunjanin.
Athletic snatched sixth place despite conceding an equaliser to finish 2-2 with Getafe.
