Frustration within the Manchester United squad has grown because of manager Ole Gunnar Solskjaer's reluctance to rotate, sources have told ESPN, with some squad players feeling they have been misled about their prospects of playing this season.
Under-fire United boss Solskjaer accepted during meetings over the summer that he had "overplayed" key players during the previous campaign, sources said, and promised members of the squad, including Donny van de Beek, Anthony Martial, Jesse Lingard, Dean Henderson, Eric Bailly, Diogo Dalot, Juan Mata and Alex Telles, that they would be more involved going forward.
In some cases, Solskjaer's assurances were enough for players to put their plans to leave Old Trafford on ice, only to be left on the sideline once the season started.
Van de Beek has played just 16 minutes in the Premier League this season, while Lingard started just one game in the Carabao Cup despite scoring two league goals as a substitute.
Mata's only start this season also came in the Carabao Cup defeat to West Ham United in September, while captain Harry Maguire had trained only once before being picked ahead of Bailly for the 4-2 defeat to Leicester City at the King Power Stadium in October.
Sources have told ESPN there is particular frustration among some fringe players that they have still not been able to break into the team despite the run of poor results.
Sources have told ESPN that Van de Beek is keen to explore his options ahead of the January transfer window, while Lingard has so far resisted attempts by the club to extend his contract, which is due to expire in the summer, because of his determination to find regular football.
Both Van de Beek and Lingard have lost their places in their respective international squads because of a lack of playing time. Everton and Newcastle United are among a host of Premier League clubs interested in signing Van de Beek on loan in January, while both Barcelona and AC Milan have registered an interest in signing Lingard on a free transfer at the end of the season.
Meanwhile, United have announced they are in "advanced" talks with the Manchester United Supporters' Trust about introducing a Fans' Share Scheme to give supporters a greater say in how the club is run in the wake of the botched attempt to join the breakaway European Super League.
A statement issued on Monday read: "We are in advanced talks with MUST about a Fans' Share Scheme which would open a path for fans to build, over time, a meaningful ownership stake in Manchester United.
"This would give fans a strong collective voice within our ownership structure and help cement a new spirit of long-term partnership between fans and the club.
"There are significant legal and regulatory complexities being worked through, together with MUST and expert advisers.
"As well as making progress on the Fans' Share Scheme, we are also creating a Fans' Advisory Board as a new channel for board-level dialogue with supporters and this is close to launch."
