Comparing his achievements in the same season, of course, Xabi is better. Kompany I think will admit that. The slight difference is that Leverkusen when Xabi came was not a strong team like Bayern Munich today. It is quite unfair to compare these conditions. Kompany should benefit more from the luxury players at Bayern Munich. With poor statistics it is natural that many Munich fans are worried. Right now Kompany just needs to concentrate on the team and his abilities. After that, it proves that the management decision was not wrong in choosing him.
Bayer's previous seasons were very bad, although they showed a very meaningful game, they could not score at all, and their defense was chaotic. That is, the team had very good potential, but there was no order, and Alonso brought this element to the team. Kompany also did not come at the best time for Bayern, but he definitely has much better conditions at the start of his work in Bayern, in addition, there are many experienced players in the team, like Müller, who could probably become an excellent coach himself if necessary.
