Goalkeeper David de Gea has dismissed reports of discontent in the Manchester United dressing room and credited captain Wayne Rooney with keeping the squad together and pulling in the same direction.
United are fourth in the Premier League table and have been heavily criticised for their stodgy performances this season, including a perceived lack of creativity and over-emphasis on possession.
The team were knocked out of the Champions League last week, leading to fresh criticism of manager Louis van Gaal and reports that senior figures in the dressing room had questioned the Dutchman's methods.
"There's a great atmosphere. The dressing room is very together and united. They are a great set of lads and we're all very happy with the group of players that we have," De Gea was quoted as saying by the club's website (www.manutd.com).
"I think that's really important in a team if it wants to achieve big things.
"This league is very tough to win and there will be a number of teams who will be in the shake-up for the title.
"That's what we all want, to stay up near the top, and to get to April and be in a position where we can win the league. That's what we're going to try to make happen."
United host 18th-placed Norwich City in the league on Saturday.
