Ralf Rangnick spoke with Anthony Martial, Amad and Donny van de Beek before they left Manchester United on loan for the remainder of the season.
Martial completed a move to second-place La Liga side Sevilla days after his key cameo in United's late win over West Ham and Amad secured a loan to Rangers, where he scored on his debut against Ross County.
Van de Beek ended a chastening 17 months with United by joining Everton on deadline day shortly after the club installed Frank Lampard as their new manager.
