At the age of 32 years it seems that it will be difficult for De Gea to find a new club I mean the club at the same level as Manchester United
He was approaching retirement while there are more young goalkeepers who are ready to replace him it will be difficult for him to compete
I also heard that one of the teams from the Saudi League was interested in contracting De Gea but this rumors cannot be confirmed.
Even though last season De Gea still managed to get the Golden Gloves award with a clean sheet 16 times, Manchester United is certainly quite wary of his performance next season whether it can be the same or not and maybe they are more trying to find a replacement this summer. The age of 32 is already entering the age of declining performance and it's no wonder why Manchester United doesn't want to fully retain De Gea. Moreover, even if he gets the chance to play at another European club, it will be quite difficult, considering that some of the blunders he made last season were also one of the judgments of other clubs if they wanted to sign him.
The only option for De Gea at the moment is to leave Europe and try to join other European players who have previously joined a Saudi league team. What is clear is that De Gea's name is very well known and that could be a consideration for the Saudi league team if they want to sign him.
