Kompany should given a chance and let us see what he gat for Bayern next season. It is not good to underestimate a coach because he did not win trophies during his days as a player. He might be able to do well in coaching. This was the same way we all critized De Rossi, but he was able to surprise us by winning his first five matches and only lost to Inter. So I think we need to see what Kompany will be able to do, if he will be not be able to win a trophy to Bayern next season like just like he didn'twhen he was as a player
Doubts for young coaches and new coaches will definitely remain for anyone as well as what happened with Xabi in the last 2 seasons when replacing Seoane but indeed it was ultimately not a problem as long as Kompany could convince in terms of performance then his views would change so if Kompany is finally at Bayern then indeed he must be prepared for the pressure he will experience.
At least, if we consider what has happened so far, regarding great players like Lampard, Gerrard, Rooney and maybe many more. They were successful as players and became legends, but when they became coaches, in reality they failed. But even so, at least there are also great players like Xabi Alonso who is great as a player but also successful as a coach. Meanwhile regarding Vincent Kompany, at least previously Vincent Kompany was only the head coach of Burnley and of course, there it might be difficult for Vincent Kompany to produce good results due to lack of resources. But at Bayern Munich, of course the resources that Bayern Munich have are good and thus, it is possible that Vincent Kompany can succeed in providing the best results for Bayern Munich next season. Although indeed, at least I will still doubt it, but let's just wait and see how the results will be, whether good or bad.
