Vincent Kompany didn't bring magic to Bayern Munich, that's the natural result they got with the strongest & most expensive squad in the Bundesliga. He couldn't give his best when he was at Burnley because the leagues in England were too competitive, it was difficult to make a miracle like the one Ranieri made when he helped Leicester win the PL.
Exactly, after all, it is very different between Bayern Munich and Burnley. Bayern Munich is a big club that is already strong, has a lot of money, and many players are stronger than Burnley. While Burnley, in the EPL, their competitors are indeed tighter, and there are many strong EPL clubs. While now at Bayern Munich, Kompany should be able to have much more potential. We'll just have to see how it develops in the future.
Not only you, I think there are many other people who agree with me, a single grape can't be compared to an apple, that's the metaphor. Vincent Kompany's burden is also heavier now, he's forced to unleash all the team's potential because management has spent a lot of money on Vincent Kompany's various plans.
However, the results of latest match can't be used as a reference that now Vincent Kompany is taking Bayern Munich to a better path, just look at how the match went, it was not an easy win and they had to turn things around to get the full 3 points. In other words nothing impressive so far.
