The winger will see his side play against Bundesliga champions Dortmund on May 12 for the final before they get to face Chelsea in the Champions League final a week later.
With the league campaign coming to a close, he is afraid that his team-mates could drop in their training intensity and he believes that this could prove disastrous in the club's bid to complete a European cup double.
The Bavarian club ended the season eight points adrift of Dortmund but had Robben scored a vital penalty late in their game against Dortmund in April, things could have ended differently.
And so the Dutch international called on his side to do their utmost in order to give their fans something to cheer about.
"We are all raring to go. We are professionals and want to win things. We have two big games coming up now. First the cup final against Dortmund, and then the big one," Robben was quoted as saying by TZ.
"We have to be ready for it and need two perfect games. I expect two very close matches where the small details will be decisive."
Last year, Bayern were third in the standings by the end of the season and were eliminated by Schalke in the DFB Kopal Cup semi-final. Should they win the two competitions this year, this will be the first European cup double in the club's history.
