Barcelona coach Ernesto Valverde has warned fans their expectations could be unrealistic.

Valverde, however, concedes they're expected to win everything this season.

He said, "There was a season when Barça won everything there is to win and another in which they won five out of six competitions so you always tend to aspire to winning everything... but winning everything is extremely difficult.

"Of course it is an obligation that we have here at Barça and we always want to win every competition.

"The way I see it, the best way to have a chance of winning everything is to be the best from the first day of the season to the last but even that only guarantees you of winning the league. Because in the Champions League or the World Cup, you can win or lose in the pace of 10 minutes."
