Kompany is new to the business but that doesn't mean he can't be up to the level of coaches like Pep Guardiola, Ancelotti or even Mourinho, he has made some mistakes but he's still on track to me. And for Kompany to last long as the manager of Bayern Munich I think winning the champions league will give him full ground at Bayern. For some coaches that started with with him like Lampard and Rooney (as ex footballers) I think Kompany is the best among them all, he just need to give the club something they have lost and that's the glory of Bundesliga, getting them that trophy is going to be a big win for him and I don't see the management sacking him.
Vincent Kompany's performance had exceeded my expectations. His appointment as the coach as one of the most prominent football clubs in the world without any solid experience. I had expected that he might be sacked before the middle of the season. But he has done well by keeping the club at the top of the table and a slightly fair place in the Champions League.
Lampard was tipped to be a successful coach based on his performance in Derby County but his time in Chelsea and Everton was not successful. Rooney had an even worst career since he has not been successful in the clubs he has handled.
