Manchester United goalkeeper David de Gea has sent his teammates a bullish message with regards to their Old Trafford futures following a disappointing season.The Red Devils finished the 2021/2022 campaign outside the top-four without a trophy, and reached a new low by losing to Crystal Palace 1-0 on the final day (May 22).New United manager Erik ten Hag was in the stands to watch on as many of the players put in a performance that would certainly not have impressed the Dutch tactician.De Gea's performances have been heralded throughout the season as he has saved his side on occasion from further disarray. He has commented on what the future holds for many in the United side who may be looking to move to pastures new.He told reporters (via Fabrizio Romano)"Ones who want to stay, stay at the club. Ones that don't want to stay go out. You don't have to stay here."Fabrizio Romano@FabrizioRomanoDavid de Gea confirms his plan to stay at Man United: “I want to forget this season and be 100% ready for next season.
