The Poland winger is eagerly anticipating this weekend's showpiece and has little doubt Dortmund has the quality to emerge victorious.
The winger realizes that the Bundesliga champion will pose a stern test for BVB, but has stressed that the club has shown in recent encounters that it is capable of getting the better of its arch rival.
"In this particular match, what will be decisive is the form you're in on that day, and we've shown that we know how to play against Bayern, that we respect this team," the Poland international told the official UEFA website. "For sure they're a very good team, but we also know what abilities we have, and we'll do everything to show our skills.
"There are many different theories you could try to find here, but in the end we'll see on the pitch who is better, who is in better form on a given day. This is the culmination of this good season in the Champions League, and every one of us is waiting impatiently for the final. I think it'll be a happy final, and that we'll be winners after this battle."
