Ole Gunnar Solskjaer has warned he will have to field weakened teams that could affect the battle for Champions League places due to Manchester United's fixture pile-up.
Solskjaer is unhappy that United have to play four times in eight days, including two games in the space of 50 hours against top-four rivals Leicester and Liverpool next week.
The United manager insists he will protect his players against the risk of injury and rotate his squad, even if that means upsetting clubs who feel United aren't putting out their best team.
