Manchester United manager Ruben Amorim said on Friday that a series of outcasts from his squad could be handed a "new life" at Old Trafford if they do not secure a move before the transfer window closes.
Alejandro Garnacho, Antony, Jadon Sancho and Tyrell Malacia have been made to train away from the United first-team squad.
Interest in the quartet has not progressed due to United's valuations and Amorim hinted they could feature in his future plans if they remain at the club beyond the 1 September transfer deadline.
Garnacho has been strongly linked with a move to Chelsea, while Real Betis are keen on bringing back Antony after his successful loan spell last season.
Interest in Sancho is complicated by the winger's reported £350 000-a-week ($470 000) wages.
"I know that it's not a good thing to have players in this situation, but it's clear they want to play in a different club," Amorim said on Friday.
"So, we try to arrange everything for both parts to be happy. I have to try to have the training with the guys that I think are going to be the future.
"Then the other guys are training and preparing for the next chapter.
"When the window is closed, it's a different history. When the window is closed, we have to receive the players and then a new life. Anything can happen."
Despite a positive performance, United's Premier League season got off to a losing start in a 1-0 defeat to Arsenal last weekend.
Goalkeeper Altay Bayindir was at fault for the only goal, scored by Riccardo Calafiori.
Amorim left out Andre Onana after a hamstring injury meant the Cameroonian missed the majority of pre-season.
Onana is expected to come back into the side for Sunday's visit to Fulham, but Amorim refused to confirm that change.
"Onana is ready to play like last week, so we will see in the game who is going to be the goalkeeper," added the Portuguese coach.
