I don't see there's a position that Bayern Munich lacks of except the goalkeeper. Neuer is no longer a good player, the second goalkeeper i.e. Ulreich is also a rubbish. I wish Kompany would sign De Gea considering there are no many good goalkeeper in this generation, or at least Kompany could ask to loan Kepa, Real Madrid already have three goalkeepers, so they have more supply.
Neuer has proven his ability so far under the Munich goal, so it is not appropriate for Kompany to immediately throw him away, in my opinion Neuer position as a goalkeeper is still very worthy of being maintained by Kompany but indeed they also have to find at least one more goalkeeper to make competition occur in the main goalkeeper position later, recruiting a new goalkeeper of course will not make Bayern Munich better if it is indeed them Nor did he experience any performance improvement and aggressiveness next season in competing as title challengers.
In addition to needing at least one new goalkeeper, of course Kompany must also try to improve their defense which indeed this season has not looked good enough, because in several Bayern Munich matches this season it seems that they are often too easily exploited by their opponents, next season at least Kompany should be able to get 1 or 2 players who can indeed defend quite well especially reportedly Kimmich is currently heading for the exit from the Allianz Arena.
