PSG has already agreed on a deal with another goalkeeper, Lucas Chevalier from Lille, to prepare for life without Donnarumma. Manchester United has reportedly started negotiations with PSG to sign Donnarumma before his contract expires at the end of next season.
Other English clubs, Chelsea and Manchester City, are also interested in signing Donnarumma. However, Manchester City has recently re-signed a goalkeeper from Burnley, James Trafford, so it's unclear if they will pursue Donnarumma further.
Donnarumma has also received offers from Al-Ittihad and Galatasaray, with both clubs offering him a significant salary of €20 million.
