Manchester United boss Erik ten Hag has praised his players handling their busy schedule.
United go to West Ham on Sunday night.
"It has already had an impact on the whole season, and we are doing quite well with the schedule," Ten Hag told reporters. "Not only quite well, really well. We have a big disadvantage compared to others. West Ham United have the worst schedule, but we have shown all season already that we are very strong physically and mentally."
He added: "That is the great advantage. Playing in the Champions League, you have a better week.
"You have to be ready for every game. If you want to be in four competitions, you have to be so prepared and have so much energy with a good game plan.
"You have to go every game again, and you can't do it at 99 percent; it has to be 100 percent, and it has to be for the full 95 minutes. We like it, and that is why players like it, but it costs energy. That is our job, and we have to take it. Sunday we go again, and I'm sure we will be there."
