David De Gea was one of the highest-paid goalkeepers in Europe. But his performance has reduced drastically in recent times, yet he still wants the same wage. Manchester United is unwilling to grant him such a lucrative contract. Andree Onana will be a better and cheaper alternative. He is still young and will spend more time with the Red Devils. If the deal to bring Onana fails the club might consider bringing back the loaned Dean Henderson from Nottingham Forest and also put much effort to sign the Japanese international goalkeeper Zion Suzuki.
De Gea's performance is not too bad He is even included in the ranks of the 4 best goalkeepers in the Premier League based on the number of goals conceded after all the success of Manchester United finished in 3rd place was due to De Gea's efforts it's just that Manchester thinks his ability will slowly decrease and they need to regenerate. I agree if the salary should be lowered and allocated to a new goalkeeper unfortunately De Gea did not agree and had to be released.
De Gea has indeed expired his contract since last month. And currently De Gea has a player on a free transfer status. But even so, Manchester United still seems to maintain a relationship with De Gea. Because it is reported that if Man Utd fails to bring Onana, it is very likely that Man Utd will return to negotiations with De Gea. So Man Utd asked De Gea not to be too hasty in choosing the club he would visit. But now De Gea is also getting offers from Arab clubs. if I remember correctly Al-Nassr is a club that wants De Gea. but it seems there is no further news about this. Plus last week Al-Nassr had some problems with FIFA which could even make Al-Nassr unable to register the players they managed to bring in if FIFA really sanctioned Al-Nassr.
The young goalkeeper from Japan, Zion Suzuki, will only be used as a second line goalkeeper. And not to be the main goalkeeper. So Man Utd's target for the main goalkeeper remains Onana or look for someone else. if it fails then Man Utd will try to re-sign De Gea.
