When Kompany first came to Bayern Munich, many doubted his capacity as a coach. Not without reason, because before coming to Bayern Munich Kompany coached the Burnley team which ended in relegation because there were no quality players but now he is at Bayern Munich he has everything so he can apply the strategy he has and succeed even Bayern Munich will soon win the Bundesliga title.
That is the reason why Kompany is better at Bayern and is sluggish in the previous club league. The reason is, Bayer with a team that has good finances and classy players, or you could say he is just continuing the previous era and applying the tactics he has. Even now he still has the opportunity to win the champions league even though it is difficult but it does not rule out the possibility that it could happen.
Most football fans didn't actually doubt him, infact most of us knew he would perform well because Bayern Munich is an already made team, coaches really don't need to do much for the success to start coming and showing. His Burnley team were no match for most teams in the EPL that's why he struggled. If you remember before Kompany's Burnley team qualified for the EPL, in the Championship they were rocking it like no mans business, Kompany was already making his name with a team that wasn't really a good match for most teams in the Championship then. But he surprised most of us back then that's why when he picked the Bayern Munich job, we knew sooner or later he was going to strive with the team.
Bayern Munich was an already made team not anymore. Now they are like any other team that i know competing in the Champions League. Any coach that is not good at his job will not win a title if he dont do better. Not minding the level of players you have, a coach guidance and tactics is needed for any team.
I like Kompany because he is doing a very good job this season at Bayern Munich, wining a trophy this season is a well honor to the coach.
