The Blaugrana find themselves nine points clear of second-placed Atletico Madrid in La Liga, are in the semi-final of the Copa del Rey and have a last-16 tie against AC Milan in the Champions League.
And the 26-year-old is not short in confidence, as he insists Tito Vilanova's men can emerge victorious in all three major competitions.
“I think we’re in a good position to lift all three trophies. We’ve got ambition, desire and talent, which in general are the ingredients you need for victory," he told Fifa.com.
"I think that, in the Copa del Rey, Champions League and La Liga, we’ve shown the kind of level that makes us believe we can be champions.
“We’re taking it game by game, and we’re training very hard and training well. The way you train is the way you play, and in the end if you train well, you’ll play well."
The former Manchester United player went on to say that the 16-point gap over rivals Real Madrid in the league came as a surprise to the team.
He added: “You never expect it, and it’s clear that nobody expected it this time. Real had just won the league and they have a great team. It’s a very significant gap but you can never take it for granted."
