Regarding the many people who doubt Vincent Kompany, I think that's normal.
And I am personally quite optimistic that Vincent Kompany will be successful next season, now Bayern management is fully supporting him for the players he wants, that is a positive thing.
Most people may still doubt Vincent Kompany because they haven't seen his achievements as a coach so far, but again, if we look at the achievements of other great coaches, of course at the start of their careers, the same thing is always doubted, so it's natural and won't stop him. Vincent Kompany's move is also because he will not continue his current job, namely making Munich dominate the Bundesliga again in the new season, at least this achievement is more than enough and he doesn't have to push to reach the UCL final next season, let alone win the UCL trophy.
Shopping for the players that Kompany wants must also get financial support so that there are no obstacles whatsoever and at least this can enable this team to achieve the desired target next season. I don't know what agreement was reached by Vincent Kompany and Munich management whether it must achieve important targets. like the UCL it seems that it will take time and will definitely be difficult, it is not that easy for Vincent Kompany to adapt to the players who are still in the main squad at the moment, let alone the new players who will be recruited, one season is not enough.
