Kompany must be thinking the same thing to add some players to strengthen the position that may still be a gap in Munich's game. In the Bundesliga they appeared very strong but unfortunately their struggle in the Champions League did not bring them to the top match.
No need to regret because it's all over. They have to focus on improving in the next season. They also have an agenda for the Club World Cup, Munich may be able to show some changes in the competition.
The Champions League is not easy so in the end by looking at this condition of course we realize that it is not only about the players who must be upgraded but also in terms of other aspects such as mentality and game patterns that sometimes always become an obstacle.
Bayern is still one of the best clubs in the Champions League but their game pattern does look the same where they too often emphasize the style played in the Bundesliga and Champions League.
Direct attacks, although very good, have gaps where the defense will lose balance and that might have a big impact because of the difference in strength in the Bundesliga and Champions League which makes the results different.
We can see how they lost to Aston Villa because of a quick counterattack where Aston Villa was smart in taking advantage of the momentum when Bayern's direct attack had many gaps because the defense that helped the attack was unable to return and this must be a concern of course.
Kompany must think about strengthening his game strategy. Especially to face strong teams in the Champions League. This season, he must see how the weaknesses and potentials are most prominent in the team he has. Building a team is not easy to be able to dominate all competitions. They may have failed in the Champions League this season, but they showed that they can still compete, which I think is not inferior to other teams. Because in reality the teams competing in the Champions League are indeed the strongest teams in Europe.
