Harry Maguire appeared to be in contention and competition for the starting position in Eric ten Hag's first season, favored by Raphael Varane, Lisandro Martinez, Victor Lindelof and even Luke Shaw in central defence.
Meanwhile, Bruno Fernandes wore the armband for several games last season and appears set to be named permanent captain for next season after Harry Maguire revealed Ten Hag had told him he was no longer captain.
The former Leicester City player said he was informed of the decision during a meeting and, despite his deep disappointment, expressed his pride and best wishes to whoever will be the club's next captain.
A new report from the Daily Mail claims Harry Maguire wants to stay at Old Trafford and fight for his place, while he is also still seen as an important figure within the team.
Manchester United will not force him out of the club as he remains happy but will listen to offers of £40m for him.
Newcastle United and Tottenham Hotspur are closely linked, but West Ham are also interested in Harry Maguire and have greater financial resources after selling captain Declan Rice to Arsenal for £105m.
However, it is likely that Harry Maguire will have to take a significant pay cut as he currently earns £200,000-a-week.
If Manchester United let him go, they would save around £20m because Maguire has a two-year contract with Manchester United.
In order to maintain his fitness and his life, the 30-year-old trained three times a day at a private camp in Portugal, coached by Ricardo Carvalho, before joining his counterparts at Manchester United for pre-season.
