The goalkeeper of the current Premier League leaders believes the spirit in the dressing room at Old Trafford has helped the side maintain their seven-point advantage at the top
Sir Alex Ferguson's side enjoyed a fruitful festive period to take ten points from a possible twelve, keeping a seven point cushion between themselves and rivals Manchester City.
While the Danish goalkeeper has faced stiff competition from David de Gea for the No.1 jersey, he says it as "a joy" to play for the club and is looking forward to the future after a gruelling winter schedule.
"The team spirit is as high as I can remember since I came here," he told the club's official television station MUTV.
"We have done tremendously well over the Christmas period and picked up some great results, only dropping points against Swansea - which was a game that we should have won in my opinion.
"We have done brilliantly and you can see that in the team spirit as well, people are happy and there’s a good, friendly and funny atmosphere in the locker room. It's a joy coming into work at the moment."
Lindegaard revealed that while preparing for games during the clogged festive period is not as difficult as some may think, the mental pressures are tough to face, especially at such a big club.
He continued: "Training is not hard work during the Christmas period because we have so many games. We just come in and prepare for the next game and then we go again.
"The games are obviously very hard, but the training in itself is not as hard as during other parts of the year.
"Mentally it's a very hard period and I think the Christmas programme this year has been tougher than others while I've been at United.
"But it's a good feeling to come out after New Year's Day with a lot of good results, a good atmosphere and sitting at the top of the table. We can now focus on the next games and getting more good results," he added.
The fixture congestion over the Christmas period saw Manchester United play four games over ten days, in which they scored 11 goals and conceded only four, keeping back-to-back clean sheets against West Brom and Wigan.
