Bayern Munich winger Franck Ribery has admitted the Bavarians have lost focus since they were crowned Bundesliga champions against Hertha Berlin on March 25.
The Allianz Arena side have won just two of their last six games, but the France international believes their recent slump is only human nature as a result of their recent domestic success.
"Perhaps we were crowned champions too early in the season. It has affected our focus," Ribery told ARD.
"We are not machines, we're all human beings. We get tired as well.
"Each and every player wants to win every game, but that's simply not possible. We have to play as a team every game. We are playing for ourselves and for the fans, to gain confidence and rhythm.
"And we are Bayern, so we must win each game."
Bayern will be looking to return to winning ways in Bundesliga away against Eintracht Frankfurt on Saturday after losing their previous two league games versus Augsburg and Borussia Dortmund.
