The Red Devils announced over the weekend that Antony will delay his return to the club "to address allegations" of assault made against him.
The 23-year-old, who was dropped from the Brazil squad, has been accused by his former partner of attacking her on several occasions, while two other women have also made allegations against the United forward.
Antony recently spoke in an interview on Brazilian news network SBT to deny the allegations of assault and intends to "produce the proof" to ensure people "see the truth".
Meanwhile, the future of fellow winger Sancho is also believed to be up in the air following his off-field feud with Ten Hag during the international break.
Ten Hag revealed after the defeat to Arsenal on September 3 that Sancho was not named in the matchday squad due to some disappointing performances in training.
Sancho then took to social media to criticise Ten Hag's comments, stating that he has 'conducted himself very well in training' and has been made "a scapegoat" by the Dutchman.
The 23-year-old is now set for showdown talks with Ten Hag to discuss his future at Man United, and it is understood that the winger wants to leave the club and could be grated his wish in January.
With both Antony and Sancho unlikely to represent Man United anytime soon, reports emerged on Monday evening that the Red Devils were considering a surprise move former Aston Villa and Everton winger Anwar El Ghazi, who is currently a free agent.
However, it is understood that Man United do not hold an interest in the 28-year-old Dutchman, and will instead turn to players from within their current senior and academy squads.
Indeed, The Mirror reports that Ten Hag is set to hand 21-year-old Pellistri a prominent role in Man United's first-team squad.
The report adds that the Red Devils are confident that the winger is developing into a promising player for the club despite his lack of first-team experience.
Man United are also said to be working on extending Pellistri's contract, which is due to expire in June 2025.
Pellistri, who was linked with a loan exit from Man United throughout the summer, has made only 12 senior appearances for the club since joining from Uruguayan side Penarol for around £9m in 2020, including 10 across all competitions last season.
The youngster has since made two substitute outings in the Premier League this season, featuring for a combined 18 minutes in games against Wolverhampton Wanderers and Tottenham Hotspur.
