Man United have also set a price tag for Fred, according to reports.
Manchester United manager Erik Ten Hag is reportedly unhappy with Dean Henderson after the goalkeeper's comments last summer.
Henderson spent the season on loan with Nottingham Forest after becoming frustrated as backup goalkeeper to David de Gea.
The England international is due to return to Man United for pre-season training but is unlikely to be in Ten Hag's plans even if De Gea leaves, according to reports.
Meanwhile, in other transfer news, the club are said to have set a price for Fred amid interest in the Brazilian midfielder.
Erik Ten Hag is reportedly unhappy with Man United goalkeeper Dean Henderson.
The Manchester Evening News report that Ten Hag is 'pissed off' with Henderson following comments the goalkeeper made last year.
After signing for Forest on loan last summer, the 26-year-old spoke about the new Man United manager in an interview with talkSPORT.
The one-cap England goalkeeper said that he didn't want Ten Hag to see him train, as he believed the coach would then try to keep him at Old Trafford.
"I didn't really want the manager to see me in training because I knew he'd probably want to keep me," Henderson said.
"I told all the hierarchy: 'I need to go and play football. I don't want to be playing second fiddle'."
Henderson now reportedly has little chance of becoming Man United's number-one goalkeeper, even if De Gea leaves.
The Spanish 'keeper will be a free agent at the end of June and has yet to agree on a new deal with United.
Man United set transfer fee for Fred.
Elsewhere, Man United are expecting Fulham to bid for Fred, according to the Telegraph.
The Brazil international, 30, has one year left on his current contract, and there has been no talk of a new deal.
Fulham manager Marco Silva is a fan of the midfielder, however, and would like to sign him for the Cottagers this summer.
Man United reportedly want £20m for Fred, who joined the club for £55m from Shakhtar Donetsk in 2018.
Sky Sports News said the price tag is 'prohibitive' to turn clubs off bidding for him. Yet, the Red Devils would lose Fred for nothing next summer if he does not extend his contract.
The midfielder has made 213 appearances for the club and scored 14 goals.
"I didn't really want the manager to see me in training because I knew he'd probably want to keep me," Henderson said.
"I told all the hierarchy: 'I need to go and play football. I don't want to be playing second fiddle'."
