Barcelona coach Xavi insists a late title push is within reach after victory over Osasuna.
However, he admits they need Real Madrid to slip up.
"La Liga is very difficult to win, or even to win at the Bernabeu," said Xavi.
“They (Real Madrid) have only lost two games this season and we would need them to lose three or four more.
“We cannot be too optimistic about our chances."
