Manchester United manager Ole Gunnar Solskjaer has hit out at the scheduling that will see Sunday's FA Cup semi-final opponents Chelsea have 48 hours longer to prepare.
United face Crystal Palace in the Premier League on Thursday, while Chelsea head into the encounter having beaten Norwich City on Tuesday.
"There is a concern that they've had 48 hours more rest and recovery than us. It's not fair," Solskjaer told reporters.
"We spoke about fair scheduling going into this restart. I have to think about Thursday. We have to win that one and then let's pick up the pieces after that."
However, Solskjaer said his team were in good shape to deal with the upcoming schedule.
"The next two weeks will be hectic, but we're very fit. Our lads haven't felt as fit as this for years," he said.
As well as direct opponents in the FA Cup, United and Chelsea are also in the battle for a top four place in the Premier League.
The Blues currently sit third on 63 points with two games remaining, although fifth-placed United can close the gap to two points with a win over Crystal Palace.
