Real Madrid manager Carlo Ancelotti believes the La Liga title race will go down to the final game of the season.
"La Liga will be decided in the final match," said Ancelotti, whose side play Barcelona at the Nou Camp on 22 March.
"We have to focus on the two-point lead we've got, which isn't much, but a lead we must make the most of."
Despite being crowned La Liga champions a record 32 times, Real's title in 2012 is their only league success in the last six seasons.

Real's city rivals Atletico Madrid drew at Sevilla on Sunday and the defending champions are now six points off the pace, meaning La Liga looks as if it will be a race between the two old rivals over the final 13 games.
Madrid looked set to retain their four-point cushion over Barcelona when Cristiano Ronaldo's penalty put them ahead against Villarreal but the visitors - sixth in La Liga - levelled through Gerard Moreno.
Ancelotti admitted he was "not satisfied" with the result, blaming slow build-up play in the first half and lamenting the fact his side did not take more advantage of their 25 attempts at goal.
"It wasn't impotence, because we created a lot of openings. We were unlucky, but we played a good second half," added Ancelotti, who has won the title in Italy, England and France.
"If it was a physical issue, the dip would be in the second half, not in the first. We had difficulties with the tempo and in finding an attacking solution other than a cross."
