Manchester United head coach Erik ten Hag is refusing to bow to demands from his players.
The Red Devils have experienced a mixed season that sees them in sixth place in the Premier League.
Despite being level on points with Tottenham, who are in fifth, Ten Hag is facing a challenge to keep his squad together.
Per The Mail, Ten Hag has fielded several complaints from members of the club's leadership group.
Senior players are not happy with their workload, with particular issues stemming from a lack of rest days.
Luke Shaw, Marcus Rashford, Raphael Varane, Casemiro, Lisandro Martinez and reserve goalkeeper Tom Heaton are a part of this group, per the source.
