It is the coach's astuteness to be able to include or create chemistry between senior players and young players in one team for future regeneration and also to maintain the stability of team performance, this is a difficult thing but it must be done.
So far, I see Kompany has not dared to maximize young players and he also does not dare to take big risks against the team's stable performance.
However, for friendly matches, of course Kompany must do that and find a way how he can rotate players without disrupting team performance, it must be maximized in friendly matches.
We have few coaches those have enough quality to bring players into their best with Kompany is having first season here at Bayern Munich, and he is looking for his mark which is surely big problem his first priority is ending this season with trophy which can give him huge success in rest of his career just because of this we have no big experiment from him even as Bayern Munich management done gamble he is not doing things like these and going ahead with available squad which is also not bad at all.
But, one thing is sure once we have success for him e can his best in coming years because after having experience and success he could be more brave enough for doing things which will give him better results, and he will be able to have young and experienced players for staying into good spot.
