Kompany is a good coach and nobody saw those qualities in him, until he came to Bayern. There are also some ex-players that became a coach and they are doing pretty good. Look at Inzaghi and Xabi Alonso in their respective clubs, they both won their domestic leagues last season. I am happy to see Kompany doing great with his new clubs despite all the critics he had in the beginning, when he was appointed as Bayern coach.
Sometimes big challenges gets people to transcend and exhibit some other talents and abilities, before now kompany was not seen as one who can be able to really head Bayern Munich and get the kind of results he's getting at time because he's been heading smaller teams before now so the confidence handling a bigger team was one most persons found difficult to build in him but so far he seem to have proven the world wrong and with time he's even advancing and breaking limits, I'm optimistic that by his second season at Munich be will be such that other's would likely envy and admire a lot.

The Belgian coach made quite a surprise, because as a new coach, with Bayern Munich he was able to match the record of the famous coach Pep Guardiola, where he was able to win 26 points from 10 matches, besides that he was also able to appear crazy with Bayern Munich with the big wins that he got in several matches.
and it is natural that some people are quite doubtful of Kompany when he decided to handle a big club like Bayern Munich, because he did not come from a famous club or a big club, he was a coach who previously handled Burnley in the second caste of the English Premier League, one of his achievements was bringing Burnley to the main division of the English league. He was named the best coach in the EFL.
and hopefully with Bayern Munich, Kompany can perform even better in the future, making more history and records as a coach to silence those who have been doubting him.
