Manchester United boss Louis van Gaal calls "ridiculous" the busy Christmas period in the English Premier League.
The Red Devils will play seven games in the coming weeks including a tough away game against Tottenham Hotspur on December 28 and the Dutchman says he is forced to rotate his team to cope with the schedule.
"It [rotation] is probably a solution for that problem, because a lot of matches in so few days is, in my opinion, ridiculous," van Gaal told MUTV.
"That is why I think I have to rotate, but then the players have to be fit and not every player is fit with us.
"We have to play these two matches [Newcastle on 26 December and Tottenham on 28 December] and that is normal in the Premier League. I cannot change that."
Asked if striker Radamel Falcao will be in the starting line-up against Aston Villa on Saturday, the manager said: "He shows fitness in the training sessions.
"Maybe I shall select him for the bench, or maybe I shall select him for the lineup. Wait and see."
