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.
