Indirectly, he made the club that wanted to sign him give up because they were unable to pay the large salary he wanted. De Gea is still able to play at a high level, his reflexes are still very good, the problems that occurred at Manchester United have made him a player without a club until now. De Gea quality can still be relied on, it's just that he hasn't lowered his salary level which makes it difficult for him to find a new club. De Gea abilities are wasted because no club is interested in recruiting him. This transfer market must be used to find a club that is willing to sign him, but he must be willing to cut his salary if he wants to continue appearing on the field.
I agree that age factor is also favouring him for playing 2 or 3 years but his salary package which was given by Manchester United is not affordable for any other club so just because of this currently he is without any club and most chances if he still insists for this package I have strong feeling no club will try to contract with him and having player like this class into their club.
There were few rumours about his departure to Saudi League, but he is not having any intention because we have no updates about him with things are clearly indicating he wants to stay here in Europe but with his own demands which are surely not easy for the clubs which are having no luxurious things like Manchester United.
De Gea career journey looks like it will continue next season, the former United goalkeeper often uploads training videos on his personal social media account, but until now there is no clarity regarding his future. His age is still considered suitable enough to play in Europe, but the main obstacle lies in the amount of salary he wants. Last season United had the desire to propose a contract extension for De Gea, but an agreement was not reached because De Gea did not want to reduce his salary.
The Saudi Pro League could be a solution if De Gea wants a large salary, but reportedly De Gea is reluctant to move there for family reasons. Al Nassr is reportedly one of the clubs that wants De Dea services, they are improving the depth of their squad after failing to win a trophy last season. Previously, De Gea was linked with several elite European clubs, but until now there is no definite clarity regarding these rumors. On the other hand, I don't think De Gea will return to play for United next season, although that's not a bad decision.
