The Ivory Coast international is determined to stop the Bavarians from completing the final leg of their historic treble by beating the odds in Berlin this Saturday.
Jupp Heynckes' men have already wrapped up the Bundesliga and Champions League and will be looking to make it three out of three at the weekend, but the defender is insistent that Stuttgart will do its utmost to cause an upset.
"Bayern are obviously the favorites, but we will get our chances as well. We head into the game with the intention to show that we can compete. We are relaxed and optimistic," Boka said. "We have to make sure that they cannot play their own game. We should follow Borussia Dortmund's example in the opening stages of the Champions League final. Bayern were forced to play long balls due to BVB's pressing.
"It could be an advantage that we are the underdogs. Everything's possible in football. We have nothing to lose and can only win here.
"A lot of people think the match is already decided, but we can spring a surprise. We have always shown up on the big occasions."
Saturday's match in Berlin will also be Bayern's farewell to Heynckes as Pep Guardiola takes up the hot seat at the Allianz Arena next season.
