But he has been unable to guarantee Fosu-Mensah regular action at Old Trafford this season and United have decided to make him available for loan.
Fosu-Mensah broke into United's first team under Louis van Gaal during the 2015-16 season, making 10 senior appearances.
Apart from his abilities as a full-back, the youngster also played as a centre-back and a holding midfielder during his days in the youth academy.
Fosu-Mensah has made 21 appearances for United in all competitions having made his debut in a 3-2 win against Arsenal in February previous year.
Widely seen as one of United's standout prospects, a year ago Fosu-Mensah signed a new deal with the club that is set to run until the summer of 2020.
Timothy Fosu-Mensah attempted 41 passes in the Premier League last season.
According to the Telegraph he will join Frank de Boer's Crystal Palace and was set for a medical at the club on Monday. The Sweden worldwide is one of five senior centre-backs at Old Trafford along with Eric Bailly, Chris Smalling, Phil Jones and Marcos Rojo.
Timothy Fosu-Mensah is a talent for the future as far as Man United are concerned but there's no doubt that he will do a great job for Crystal Palace in the Premier League this season.
