Cole Palmer has appeared to back Kobbie Mainoo after the Manchester United midfielder was denied a loan exit in the final hours of the transfer window.
Mainoo, 20, was keen to leave Old Trafford temporarily in search of more regular football, but United boss Ruben Amorim blocked the request and told him to stay and fight for his place.
The midfielder has been left on the fringes this season, making just one Premier League appearance in August, and was overlooked for Thomas Tuchel's squad for this month's World Cup qualifiers.
