The Stuttgart striker is looking forward to the DFB-Pokal final but feels his side will have to be in top form if they are to emerge victorious against die Roten
Bayern have already wrapped up the Bundesliga title and the Champions League and will be looking to complete an historic treble on Saturday, but the 28-year-old has insisted his side will do their utmost to cause an upset.
"Bayern are the clear favourites, there’s no doubt about that. It’s difficult to find any weakness in them," Ibisevic told Bundesliga.com.
"Being in the role of underdogs is our chance. As I said, you've got to fight in life and I'm really looking forward to this game.
"It’s the most important game of my career so far, it’s my first final. All of my energy is channelled towards Berlin right now."
