Bayern Munich's decision to recruit Kompany is actually quite right even though Kompany was not the first priority for Bayern Munich because the management had seen several other players who at that time turned out not to have the willingness to coach Bayern Munich. But Kompany is very willing to coach Bayern Munich and I think his career and performance will be remembered very well if Munich can win the Bundesliga again this season, especially if he is able to bring Munich to the UCL final this season later.
Whether it is right or not we can see how Bayern Munich can be better than the previous season, but it is still too early to judge him even though when seen when he was Burnley coach he failed to provide something good for the team. Now the conditions are different because he is in a team that has quality players so it will be easier for him to develop the team compared to when he was at Burnley who only relied on ordinary players.
The target to win the Champions League or reach the final may be difficult because there is a lot of competition there that he will face. But a more realistic target is that he managed to return to giving Bayern Munich the Bundesliga title after the previous season was taken by Leverkusen.
