The real challenge for Kompany will come soon when Leverkusen and other teams understand the strategy Kompany uses in Bayern Munich which can make Xabi Alonso understand the weaknesses and the way they can win against Kompany and his partner. However, so far Kompany had an epic performance in the Bundesliga but I don't think if this will continue for a long time regardless of the players and potential they have in Bayern Munich. In my own idea still, Leverkusen can have a much better chance than Bayern Munich.
I think other managers (coaches) already know how to deal with Kompany's strategy. In the last 2 matches, Kompany failed to lead Bayern Munich winning the matches anymore. Bayern Munich got a draw against Leverkusen, Bayern Munich even got a defeat against Aston Villa. It is clear that other teams can destroy the strategy applied by Kompany. The epic performance in some earlier matches can be nothing if Bayern Munich can't maintain their good performance in the next few matches.
Is Kompany really the key point. The team has realized that some things have to change. Now they are running into the same problems and I wonder if they will be able to solve those problems. Kane is not the scorer they were hoping for because the scorer they were hoping for scores goals in important games, he doesn't.
