Barcelona striker Ferran Torres was delighted to prove the matchwinner after victory over Atletico Madrid.
Torres struck the only goal of the game on Sunday.
"We had to win no matter what, because it was important to win the league. We worked very well and the fans helped us," said Torres.
"They had gone thirteen games without losing, they are one of the fittest teams in La Liga. It was a game to certify that we were doing well and that we want this league and that was reflected on the pitch."
He added: "The important thing is to have chances. Then you can be more or less accurate."
