Barcelona boss Pep Guardiola will not accept anything less than victory against Almeria this weekend.
Guardiola wants his players to maintain their eight point gap on second-placed Real Madrid.
He said: "We can lose at the Bernabeu in the league, we can lose against Espanyol at home, but there is one game we cannot lose: the one against Almeria.
"We have to go to the Bernabeu with an eight-point advantage, not six or five. They (Madrid) have a great team, and it's normal that they could beat us in the league and cup. It could happen, but not against Almeria. We can't lose this game."
