Boateng is the weakest out of those 3 and Süle is probably the strongest, most Bayern fans agree on that. Next year Bayern will probably buy Pavard or they will first try whether Lukas Mai is good enough already to play on that level. Like i said before, there aren't many offensive players who are affordable and would help Bayern. Hazard, Dembele, Mbappe, Neymar, Couthino, Salah, Mane are too expansive and have no reason to change clubs. Younger players like Pulisic haven't proven so far that they can make the difference on the highest levels. I think Bayern should have bought Martial, he could have played as a winger and a striker. If Bayern would have a better coach (Nagelsmann and Tuchel were all available, Rose probably as well) then i honestly believe that with the formation i mentioned before, they still would have had a good chance at winning the champions league. Now as a Bayern fan you should pray that Tuchel/Rose takes over next season and that 2 out of Coman/Gnabry/Davies become world class or that Bayern buys another talent who then quickly becomes world class. Currently it's just unrealistic for Bayern to sign a world class winger, maybe the best solution would be to try a completely different system. Juventus doesn't have world-class wingers either and they are doing just fine.
