Maybe there is a big difference in terms of odds?
The bookies are not good deciders of how a game will end, I've seen otherwise several occasions.
I can vouch for Hansi Flick being a good coach and manager and outplaying whatever tactics that'll be used by Vincent Kompany but I can not say that for the defenders if they can hold down Bayern Munich players during that game. That defense is too weak to contain players like Harry Kane, Jamal Musiala and Co's. In between, since 2020, the last five fixtures between these two sides been won by Bayern Munich. It's high time we see a win or draw from Barcelona.
Barcelona has a good team to stand against Bayern Munich and they can definitely have the chance to beat Bayern Munich like the other games they had against this team and It will definitely be interesting to watch the game between these two teams but still, I think Flick will have a hard day against Kompany because Flick got a good team but the whole team is very young and they don't have enough experience, especially the defenders in Barcelona were too young and this can be dangerous for Flick and his player for play against players like Kane who know how to score goals for his team.
