The coach will face a difficult task, especially if they are with a new coach. Because a new coach will need adaptation, and understanding the character of each player he has will be a task that is not easy for him. He also has to be able to see what strategy is suitable, and of course there will be a disassembly of players to get the best squad in the main squad.
We'll see whether Bayern Munich will be able to restore the title they have won next season, or Leverkusen will be able to defend the title they won this season. Of course this is something we will be waiting for next season.
Kompany now has one of the best squads under his control, which should make his job easier to meet the team expectations. But if you look at Leverkusen, who will be the defending champions next season, everything still looks very difficult. Leverkusen will be the main competitor in fighting for the top of the standings, also teams like Stuttgart, Leipzig and Dortmund will certainly add to the complexity of the competition. However, next season is still very far away, Kompany still has plenty of time to prepare and do something in the transfer window.
