Manchester United are reportedly furious with Crystal Palace over their treatment of Timothy Fosu-Mensah.
Fosu-Mensah was sent on loan to the Eagles ahead of the 2017-18 campaign, and he was a regular early in the season.
The 19-year-old has struggled for football since Roy Hodgson replaced Frank de Boer as head coach, however, failing to make a single appearance for the London club since November 5.
According to The Sun, United are agitated that the Dutchman is no longer receiving first-team football, and the Red Devils are considering recalling the defender before finding him a new club.
Fosu-Mensah made 11 appearances in all competitions for United last season.
