The performance from him has been quite bad with Manchester United. De Gea is conceited a lot and I will blame the defense of Manchester United for that. I am not saying that he did not make any mistakes. Definitely, he did but the defense, especially Harry Maguire was the one to blame. I thought, after he becomes a free agent, other clubs are going to be interested in him and would take him in pretty quickly. But it seems like that is not the case. I really do not know why but clubs are just not interested in him. Could it be the salary?
For De Gea I will not think badly or prefer to think in reality if De Gea is the best player in the premier league in the past but in reality no one club wants to sign him even big complaints like Bayern Munich have never thought about a goalkeeper and if De Gea's performance is still very strong, of course after the end of his contract at Manchester United, many big clubs should make offers because he is leaving as a free agent.
The only good conclusion is that if the next transfer market reopens but there are still no offers for this player, I think De Gea will decide to retire and Bayern Munich will still keep Sven Ulreich.
