Real Madrid coach Jose Mourinho is wary of a tricky month ahead.

Madrid headed into the weekend seven points clear at the summit and Mourinho reckons the next few weeks will provide a tough test of his team's title credentials.

The Portuguese said at his pre-match press conference after training on Saturday: "We play Levante, who are fourth, then Rayo Vallecano, who have been a revelation this season, and Espanyol, who are fighting for a European spot.

"It's a complicated month for us, perhaps more for us than for our direct rivals."
