Barcelona president Josep Maria Bartomeu says victory at Real Madrid proved their players "the best in world".
Lionel Messi hit a hat-trick as Barca reignited their title hopes with the 4-3 win.
"For Barcelona this does not change anything, we have great confidence in the players. Personally I have said this for several weeks, the players once again proved they are the best in the world.
"They played very well, they had a very good game.
"Now we're just a point off the leaders Atletico and Real Madrid. Let's try in the nine games left to recover, sure. Hopefully this win means a change in the league."
