Bayern Munich really had to change the strategy they used to compete in the new season because they managed to get a very strong opponent and it was difficult to beat. As you said, the coach will indeed have a different character. Hopefully Vincent Kompany will have the opportunity to show the strategy he uses to win this season. All of this also depends on the players at Bayern Munich. If they respect and obey what Vincent Kompany said then there is a chance to win this season.
I think there are very few players who don't want to follow their coach's instructions and even if there were they would definitely be placed on the bench. Because all the players on any team must follow all the directions from their coach and also respect him like they respected the previous coach on the team, so Vincent Kompany is really required to be able to give good work to Bayern Munich next season so that Bayern Munich can compete again with all rivals in the Bundesliga and also in the Champions League next season.
