Kompany must emphasize more on the mentality of the players now and give more encouragement that in the end the Champions League is different from the Bundesliga which they have dominated since the beginning.
If Munich wants to do better next season of course, everything must be prepared from the beginning of the season. They can't ignore anything and focus on improving their mentality as well as their team's performance. A team like Madrid with a mentality that we don't need to doubt in the Champions League, was also eliminated because their performance declined. Kompany has done well this season, but surely he will set a higher target for next season. That way, of course it must be followed by the development of his team.
Bayern Munich won the Bundesliga championship this year and found itself again after a one-year break. Borussia Dortmund is no longer as good as before, their only rival is Bayer Leverkusen. They will also lose their coach next year. So I think it will be easier to win the championship next year, but transfers are a must for the team. They may not be able to win the Champions League championship with this team. If their goals are high, they should bring in good players.
