I also worry about Bayern Munich choice to fire Julian Nagelsmann and hire Thomas Tuchel. It seemed like mistake. Even with Tuchel experience he didn't do well especially compared to Xabi Alonso success. Hiring Vincent Kompany who doesn't have much experience has made people even more doubtful. While Kompany and Alonso show promise it is unfair to expect all young coaches to achieve same success. Bayern Munich slow start to season has made people question Kompany ability to lead team. Only time will tell if Kompany can prove himself and make people believe in him. May be he will be best.
This is a big gamble taken by Bayern management, but we also don't need to be too hasty to doubt Vincent Kompany because in the current era of modern coaches, many young coaches are successful even though they don't have sufficient experience, such as Xabi Alonso, who was quite successful with Leverkusen and the success of De Rossi. in Rome, even though there were doubts, the young coach was able to prove it.
Likewise with Vincent Kompany at this time, he still has every possibility to make Bayern develop, especially with the players in the Bayern squad who are quite capable.
You didn't mention Inzaghi, as one of the most successful coach too this season. Football is changing hands from old coaches to young coaches and young players are performing extraordinary and breaking records of the old players, showing that football lies in the hands of the young. Kompany will not be known to be a good or bad coach if he is not given the opportunity to coach Bayern.
Next season will tell if Bayern gambled with the replacement of their coach or not. Kompany is lucky to be given the opportunity to coach a big club, I just hope that he does not mess things up for himself in Bayern and prove that he is the right guy to manage the club.
