The trend and attention this match is carrying made me to have several toghts about the match despite the stats of Bayern been always the winning team against Barcelona in their last five matches that I have seen; it might end up been a game of how well experience your manager is which might favor Barcelona because Hensi Flick have more experience than Vincent Kompany. Barcelona might end up winning this match.
Hensi Flick does have more experience than Vincent Kompany, but that also doesn't guarantee that Barcelona can win easily in this match, because in the Champions League all coaches will use their best strategy and will tell their players to play as well as possible when the match is underway. Bayern Munich is a team that has a strong mentality in the Champions League so Barcelona needs to be careful in playing if they want to win at home when the match takes place.
