The Spain international is optimistic about his side's chances of reaching the quarter-finals of the Champions League
The midfielder has admitted that losing the first leg 2-0 was a huge blow for the Catalans, but he has little doubt that Barca can turn things around at Camp Nou.
"The team is fine. We suffered after the match against Milan. Our confidence went down and we felt that against Madrid in the Copa del Rey and the league," Fabregas said at a press conference.
"However, nobody doubts we can do it again, that we can turn it around. But it all depends on us. On big occasions, these players have always been there. The players are more than capable of playing in big games.
"If we win and play well it could be an incredible boost for the team. We have to be clever and we can’t just play with our hearts, but with our heads as well. This generation of players is due a historic comeback."
