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.
At this moment I get odds for Barcelona @2.15 and for Bayern Munich @3.00 and I think these odds are decent odds because at least, I think Barcelona has a chance to win because I also consider the work of Hansi Flick and the Barcelona squad which is getting better now compared to last season. About Bayern Munich, although still in a good trend, but I think Bayern Munich is experiencing a slight decline in performance although indeed, I also admit that Bayern Munich could win or maybe just hold Barcelona to a draw at the Estadi Olímpic Lluís Companys.
But indeed, it seems that a draw might be very possible to happen but at least, because Barcelona has Hansi Flick and also Lewandowski who previously had a big influence at Bayern Munich and now they play and work for Barcelona. So with that, I think that makes Barcelona have a good chance to beat Bayern Munich although of course it won't be easy at all.
