Kobbie Mainoo's hopes of a loan move to Napoli were blocked by Manchester United on deadline day

Manchester United head coach Ruben Amorim is not willing to let any players leave in the January transfer window unless replacements come in.

Kobbie Mainoo and Joshua Zirkzee are both keen for chances to play more regularly over the second half of the season. Mainoo still wants to go out on loan, while Zirkzee has been linked with a return to Italy.

However, even when his squad is bolstered in the middle of next month by the return to fitness of skipper Bruno Fernandes and Bryan Mbeumo, Amad Diallo and Noussair Mazraoui returning from the Africa Cup of Nations, Amorim does not believe there are enough players in his squad to cope with a reduction in numbers.

"It's going to be hard for someone to leave the club if we don't get a substitution," he said.
