Real Madrid coach Jose Mourinho won't let his players become complacent over their big lead on Barcelona.

Real Madrid went 13 points clear at the top of the table with their 4-0 rout of Racing Santander.

"We'll try to win every game and, obviously, to win the championship as soon as possible. Winning the league title by one point would be a success," said Mou.

"Our cushion over the runners-up is obviously good for us and it leaves Barcelona in a complicated spot, but they are a great side that could easily have a winning streak, so we must continue to work as hard as we've done so far."
