Manchester United manager David Moyes has admitted that he will be forced to rotate his squad for his side's games in the FA Cup and Capital One Cup.
United face Swansea City in the FA Cup on Sunday before travelling to Sunderland two days later, and Moyes has revealed that he doesn't agree with placing two important fixtures so close together.
The 50-year-old told reporters: "We will definitely rotate over the two games. It's the same for both clubs so there aren't any complaints, but I don't think that it's right to be asking footballers to play Sunday and Tuesday.
"We've done it over Christmas, and I totally understand that and the reasons why, but I think that it's a bit harder to accept here."
Manchester United go into Sunday's fixture on the back of a 2-1 defeat at home to Tottenham Hotspur in the Premier League.
