Selling Lewandowski is a thing of the past - there is no point in talking about how good it would be if he stayed or something like that. Now Nagelsmann has to work with what he has - either change the game plan, taking into account the fact that Bavaria does not have a center forward, or endure until the winter transfer window and buy Ronaldo (this will be the only option in winter). I don't see any other options given the state of the market and the frugality of Bavaria.
Agree with what you say because this has already happened and there is really no need to argue about it anymore because the most important thing now is that Nagelsmann has to rack his brain to make Bayern what it was a few seasons before.
At the moment his condition looks normal but this is quite serious for a team like Bayern because it is rare for them to get results like this in a row in one season.
