Gianluca Zambrotta says Barcelona's players are convinced they can still win a Liga and Champions League Double this season.
The Italian fullback said: "We can win both competitions, especially with Lionel Messi fit again.
"His return is very important to us in this final stretch of the season, hopefully with everyone fit, we can win both titles. It's crucial he is fit from the Champions League semis to the final at the end of the season."
