Donnarumma has no other choice but to wait for which team is serious about bringing him in because it is no longer possible for Donnarumma to stay at PSG so for his career he will go anywhere and regardless of which team will sign him and indeed personally I quite agree if Donnarumma goes to Manchester City because in my opinion both will have big advantages in terms of performance Donnarumma is still quite good and his age is still very young so it is very likely that he will be able to contribute greatly to the Manchester City team.
Yes, City is a good team, but in my opinion, they are not in their best period right now. Guardiola has initiated major changes in the team, selling many players and bringing in new ones, and it may take some time before he gets the team playing well. However, I agree that for Donnarumma, City is a very good option at the moment. But now he has to wait for the deal with Galatasaray regarding Ederson to be completed, and only after that will he be able to join City. I don’t know why, but for some reason these transfers have stalled and are not progressing at the moment.
I believe the Donnarumma transfer will be completed before the season ends. Once that's done, Manchester City can easily let Ederson go. It seems they don't have much confidence in their backup goalkeeper right now. He made obvious mistakes in the match they played. The presence of an experienced player is essential. This could be possible with Donnarumma, who has left Paris Saint-Germain.
