The second half of the season starts in 30 days and Bayern Munich are still looking for a replacement for Manuel Neuer. According to the current status, Nübel will not return from AS Monaco. They would rather buy him. Furthermore, Nübel does not get along with the goalkeeper coach Tapalovic from Bayern Munich. Therefore, I do not see Nübel coming back. Yann Sommer from Mönchengladbach is now being discussed as an alternative.
Sommer is a great goalkeeper and he shown it in Euro 2020 as well as World Cup 2022. Livakovic from Croatia is a good option for Bayern too or the goalkeeper of Argentina Emiliano Martinez.
In the meantime
Sven Ulrich, their second goalkeeper will take over the position of Neuer. Bayern will find one goalkeeper from transfer market because with only two goalkeepers, it is risky. They can get injuries in a second half of season anytime and if both goalkeepers are injured, it's terrible.
Sommer, Livakovic and Emiliano Martinez won't have too expensive price on transfer market.
