I almost completely agree with your opinion, but one thing, Kompany also wants to lead Bayern Munich to win the Champions League this season. There are many big targets that need to be achieved so that a coach becomes increasingly respected in European football, including Kompany, of course.
Wining the Champions League is indeed a good thing any coach will want to achieve including Vincent Kompany, and it is among his main target as a manager especially if he can be able to win it as soon as possible even though he have a lot of work to do as a manger because his team need some balance before they can achieve such success.
With the likes of Madrid, Manchester City, and others, it will only be a luck of Kompany was able to win the Champions League this season.
So far Bayern Munich have won 2/2 of their early season matches. Even though the opponents are Wolfsburg and Freiburg, this is Kompany's record at the start of the season. Bayern Munich is one of 3 teams that managed to get 6 points in the last 2 matches in the Bundesliga, so I don't think Kompany is really worth underestimating. Leverkusen suffered their first defeat of the season, so their performance has declined and is no longer the same as last season.
Wolfsburg and Freiburg are not small teams in the Bundesliga. Even though they are not among the top three teams, they are always tough to play against because they used to be tough and always have good squad. For Bayern Munich under Vincent Kompany to have started this great, there is a good tendency that the can do well for the team especially if he is able to win the Bundesliga this season ahead of Leverkusen and Dortmund.
