Under Ole Gunnar Solskjaer, United have implemented a strategy of signing talented youngsters in order to suppleent their development squads.
Willy Kambwala and Facundo Pellistri both arrived during the summer window, with the pair representing the club at age group level.
18-year-old winger Amad Diallo also completed his long-awaited move to United last week, following protracted issues surrounding a work permit.
Solskjaer’s side agreed a fee with Atalanta back in the summer, but were forced to wait before bringing him across to England.
Despite registering very few senior appearances in his career, it is understood Diallo will join the first-team squad at Carrington – although he will be given time to adapt.
