Barcelona president Sandro Rosell has warned fans their cycle could come to an end.

Rosell is predicting a "let down" in the future.

"They say it works in three-year cycles. We've had four years of dominance and in the fifth it is crystal clear. We'll see, but it looks good. Already we have broken the cycle of three years with this team.

"(Someday) There will be a downturn, and the mission of the club will then be to make sure it is short."
