Sandro Rosell says Barcelona still have hope ahead of the second-leg of their Champions League semi-final against Bayern Munich.
The Spanish club are on the brink of reclaiming the Liga title but their European ambitions were dealt a massive blow in Germany.
The Blaugrana were sunk 4-1 by the Bundesliga champions in Munich in the first leg, but Rosell is refusing to throw in the towel just yet.
"Is a comeback against Bayern possible? People should believe in it," he told Marca.
"Everything is possible, even this."
Barca have already produced one incredible comeback in the competition this season. The club were beaten 2-0 in the first-leg of their last-16 tie against AC Milan, before running out 4-0 winners in stunning fashion at Camp Nou in the second leg.
