Spain international insists his team will still fight for La Liga despite falling seven points behind, and asks for focus ahead of Champions League return against Chelsea
After taking a first-half lead through a close-range Sami Khedira finish, Cristiano Ronaldo scored the winner for the visitors shortly after Barca substitute Alexis Sanchez had given the hosts hope with an equaliser on 70 minutes.
Madrid now need just six points from their four remaining league fixtures to be crowned champions at the end of the season, but Busquets insists the champions will continue to fight to retain their title, while also focusing on Tuesday's Champions League semi-final second leg match against Chelsea.
He stated: "We'll give everything until the end in the Liga. But now to Chelsea - we can't give up. The fans were great, supporting the team the whole game, until the end."
Madrid's victory tonight means Barcelona have lost back-to-back fixtures for the first time since 2009, following their 1-0 defeat to Chelsea in the first leg of their Champions League semi-final last week.
