Bayern Munich was never a team with bad financial power and they could easily hire another goalkeeper in the summer with the money they can spend for it but currently, the only hope they can have is just their old and experienced goalkeeper Neuer. Neuer is getting recovered and I think he is going to play for his team soon but I don't think if we can expect to see a good performance from Neuer when he returns.
Bayern Munich's financial capacity may be abundant for the Bundesliga tournament. But compared to the Champions League, they are much weaker. Neuer will return to play soon, with his recovery going smoothly. But after a long period of being unable to play, he will no longer play as well as before. Aging is a big problem. Neuer is 37 years old. How much longer will he be able to contribute to Bayern Munich?
Bayern Munich needs to spend some money to buy a new goalkeeper to replace Neuer, which is necessary now.
