The Netherlands winger insists his side will have to "give everything" if they are to overcome Stuttgart in the DFB-Pokal final in Munich to add to their trophy collection
The Bavarians take on Stuttgart on Saturday evening as they attempt to add the domestic cup competition to their European and Bundesliga successes, and Robben has warned his team-mates to expect a tough encounter.
"This will not happen automatically, we have to work hard for everything we get," he told reporters.
"This is obviously a special game, and of course we now also want the treble as it is something no other German team has managed.
"VfB have made their way to the final, and they are also a strong team. On Saturday we have to give everything."
Robben's 89th-minute strike sealed Bayern's 2-1 win over Borussia Dortmund at Wembley, and the winger revealed he always believed in his own ability despite suffering criticism for his displays in previous finals.
"I have always believed in myself and have always done everything possible to be in shape," he added. "But, I ultimately don't care who scores the goals if we win."
Sporting director Matthias Sammer echoed Robben's sentiments, insisting that the chance for a treble is an opportunity his side cannot afford to let slip.
"We have to understand if we win, we will make history," he explained. "It's an opportunity we have to grab with both hands."
