Cristiano Ronaldo and Harry Maguire are embroiled in a power struggle over the Manchester United captaincy.
Maguire is reluctant to relinquish the armband for the rest of the season, as Ralf Rangnick looks to take the pressure off him as he wrestles with his own loss of form, for fear of losing the captaincy on a permanent basis.
Interim boss Rangnick has called on Ronaldo to mentor the young players within the squad, which is understood to have led to further friction with Maguire.
