Barcelona coach Luis Enrique has warned there's still some twists to come in the title race.
Victory at Real Madrid on Sunday has Barca top of the table.
But Enrique says: "I don't have the feeling we're favourites now.
"Madrid have a game in hand, so can move back ahead of us. Both teams will have a difficult time between now and end of the season. There will be surprises, for sure, and results people don't expect. We have to be prepared and make sure we don't slip up.
"I wish we had more games, because it would mean we're still in Europe, but I don't know if it's better or worse in terms of the league. We will have to see."
