Manchester United manager, Jose Mourinho, has reportedly ordered his players to report for training at 4.30pm on Christmas Day and has also instructed staff to come to work.
In past seasons, United trained at Carrington on Christmas morning like other clubs, before spending the rest of the day with their families and friends.
Even Mourinho’s predecessor, Louis van Gaal, gave the players and staff the day off.
A source said: “Everyone is seriously pissed off. They’ve never heard anything like it – not even under Fergie.
“All the staff are used to coming in and sorting training out at Carrington but having it at Old Trafford adds a whole new level of organisation and brings more staff in.
“Jose’s had a face like thunder at the training ground for most of the season and is clearly not happy with results.
“Some staff will even have to stay later on to sort out the pitch and stadium for the next day’s home game. He’s effectively cancelled Christmas.”
