Real Madrid goalkeeper Iker Casillas accepts they cannot afford to drop any points if they're to beat Barcelona for the title.
"Right now we are concerned about going game to game," said Casillas. "We remain on a good run, but every game now is vital.
"We cannot afford to drop any points because if we do, Barcelona would take this opportunity to say goodbye to us in the Liga.
"In the remaining two months there's still plenty of twists and turns that can happen."
