Barcelona boss Gerardo Martino had admitted that Saturday's 3-2 defeat to Valencia has altered the La Liga title race.

Valencia inflicted a rare home defeat on Barca, giving title rivals Atletico Madrid and Real Madrid a chance to overtake them this weekend.

"All the options are intact but now we begin to play a different league to what we have done so far," Martino told reporters.

"We must move forward. Next week we have two very difficult games against Real Sociedad and Sevilla. Every time we lose a game we play, we care.

"And it's much more in the league, where losing a game means losing a piece of the championship. But we will fight without any doubt and try to fix our mistakes."

Barca travel to Sevilla in La Liga next Sunday.
