Barcelona midfielder Andres Iniesta says Real Madrid remain favourites for the title.
Barca cut Real's lead to a point after victory over Getafe.
"The leader is Madrid. They have the advantage, but tomorrow has to play. Things have changed, we are fighting to join them in threes. That's what we want until the end," said Iniesta.
"These derbies are very intense, I don't know if I'll watch them."
