Manchester United boss Louis van Gaal is delighted with the team spirit inside the dressing room.
Former player Andy Cole noted in Friday's match programme that United seem a happier club.
Van Gaal agrees: "I think so, I think when you win six times in a row, and you draw, and you win again, then the spirit is fantastic.
"I think there is happiness in the club because we are together working for one goal. We have a very good communication between all the employees in Manchester United and that is very important.
"And we can celebrate parties, Christmas parties, and that is also important. We can work but we can also celebrate and that is very good."
