That's the point, they have to be a little patient in waiting for Bayern Munich's performance to return to its peak performance and maybe they won't be able to see that in their first season with Bayern Munich, because there will definitely be a process that has to be gone through. He must know the players well, including getting to know the playing styles one by one of the players he currently has in the squad. Apart from that, this is also a special note for Vincent Kompany, because he also has to show good progress if he wants to be retained for longer, he doesn't have to be champion but at least he can show a game that is nice to look at.
The fans also have to give it a chance, because it's not uncommon for fans to put too much pressure on a coach in their first season. I know what they mean because I am also a fan of a team, but they must be wiser in criticizing and be able to understand the situation that the new coach will experience.
indeed everything needs time to process, of course to adapt to each other it takes time it is impossible for them to immediately appear to be the best, even though Kompany will do his best with the tactics he has of course it is impossible for Bayern Munich to immediately recover and return with very good performance. Kompany will certainly do his best to develop and restore Bayern Munich, but they need to be patient to find their best performance. Apart from the quality of the players, of course the care given by a coach will also influence how they play on the field.
Indeed, the fans are usually impatient with the recovery or training process, they just want their team to return with good performance and become a team that dominates again, whereas they don't know what a coach should do, because even though Bayern Munich has enough players qualified but that doesn't mean it will be easy for him to develop Bayern Munich in the near future. Fans must be able to understand by continuing to support their team, including their coach, because criticism issued by fans can affect the coach and may make the coach unable to focus.
