Bayern Munich who failed this season of course they will try to rise by buying some new players who can restore their status as the rulers of the Bundesliga, indeed currently Kompany is an inexperienced coach, but to be honest we don't know what he can do later to restore Bayer Munich dominance in the league, besides that we also used to think of Alonso as an inexperienced coach but can actually bring Leverkusen It's been great this season, so maybe Kompany will be able to do that in the future as well.
I am a little doubtful about the status of their coach because as far as I can see Kompany has not shown his best abilities at the club he previously held. Being the coach of a big club like Bayern Munich definitely comes with a lot of pressure, especially as there are lots of star players, so Kompany's job will be much more difficult. Other pressures from fans and management will definitely demand more where he must be able to provide the best for the club.
Xabi Alonso doesn't have much freedom because he already knows the player's character and he also understands the condition of the player he can rely on. Leverkusen is still Bayern Munich's competitor next season and I am quite sure that Xabi Alonso is far superior to Kompany in terms of tactics and strategy.
