Previously, many of us doubted Kompany capacity to coach and many of us here underestimated his ability to coach Munich after Burnley failure to stay in the Premier League last season, but now Kompany has proven that he has the ability to coach a team as big as Munich, so as you said, of course now those who previously criticized has been silent and even started to praise him as a coach great at the moment 
.
I think it's normal if many of us are doubt about Kompany capacity as the manager of Bayern Munich this because Bayern Munich is a big team in Europa and previously Kompany too has been makes Burnley relegation to Championship division besides that Kompany never train big team before so people doubt he can bringing Bayern Munich to performing well and compete with Leverkusen for race title but he has proved it to those who doubted him that Bayern Munich can able to taking over the domination of Bundesliga and under Kompany Bayern Munich has strong balanced to attack and defense and it proven from their statistics that Bayern Munich has 47 goals and only conceded 13 goals.
