Alejandro Garnacho, Marcus Rashford, Antony and Jadon Sancho are said to be all banned from the tour of Manchester United by the US.
The outcasts are made to only train in Carrington if they have not found new parties when the tour starts in July, while Ruben Amorim wants to exercise his authority at the club.
The Portuguese boss has passed a terrible first campaign in Old Trafford, which led to 15th place in the Premier League, their lowest since the relegation in 1974.
They were also defeated by Tottenham in the Europa League final in Bilbao last month, which means that next season they will not only participate in the European competition the second time in 35 years.
The campaign was covered by a disastrous tour after the season to Asia, where the Red Devils lost humiliating to the Asean-Al stars to the exhibition, while Alejandro Garnaacho and Amad Diallo came under pressure for quarrels with fans.
A summer structure started with United with a £ 62.5 million deal for Matheus Cunha earlier this month, while they are strongly connected to Bryan Mbeumo van Brentford.
Amorim only wants players who 'die for the shirt' and therefore set to tidy the Castaway Quartet.
A club source told The Sun: 'Amorim votes his authority at the club. It was hard to arrive in the middle season, but he now has the chance to shape the team to his image. And he doesn't waste time.
'He only wants players who would die before the shirt and be on board with his ideas.
'He also wants a smaller team to create an intimate team binding, so that everyone gets enough playing time to be fitness at Peak when they are called. He doesn't want bad apples or distractions. '
The American tour of United starts against West Ham in New Jersey on July 26 less than two months after their tour after the season to Malaysia and Hong Kong concluded.
They then play Bournemouth in Chicago on July 30, before they hire Everton in Atlanta four days later.
Amorim's side face Arsenal during the opening weekend of the season and he will hope that his team was drastically improved at the time.
Although he is sure that funds are available to strengthen United, the transfer budget will be increased if they can discharge Rashford, Garnacho, Antony or Sancho.
Sancho reportedly agreed personal conditions with Napoli, but United has hit a transfer costs of € 25 million (£ 21.3 million) on the 25-year-old, who would be too much for the Italian champions.
In the meantime, Newcastle sees a shock movement for Rashford, which is banned in Old Trafford after being borrowed from Aston Villa for the second half of last season.
Garnacho is ready to leave Old Trafford after a public spit with Baas Amorim over a bench in front of the Europa League final.
Although there is no lack of interest, the price tag of £ 70 million from United has excluded a number of clubs.
