Manchester United manager Sir Alex Ferguson has reiterated he is not looking to make a move in the January transfer window unless a top player becomes available or his squad is further hit by injuries.

32414 - Fergie won't shift from transfer plans

Ashley Young this week joined an extensive injury list that includes the likes of Nemanja Vidic, Anderson, Michael Owen and Tom Cleverley, while Darren Fletcher is also sidelined for the rest of the season with a bowel condition.

Writing in his programme notes for the Boxing Day game with Wigan, Ferguson said: "All things being equal I am perfectly happy with the strength of our squad in terms of depth, quality and age range.

"I will not be swayed by the endless tweets and blogs urging the club to get busy in the transfer market next month.

"As far as I am concerned I am marching perfectly in step, true to my beliefs and principles. While recruiting some of the world's leading players can lift you into contention for honours, it doesn't necessarily take you all the way, as I hope we will be able to demonstrate before the end of the season as other factors come into play.

"You can never say never in football, of course, because fortunes can fluctuate wildly - that's the football world. If a really top-class player became available, then we would go for him, or if we picked up any further serious injuries, it might be important to add to our squad."

United have been linked with moves for Nicolas Gaitan while suggestions have been made of a revived interest in Wesley Sneijder. Bolton defender Gary Cahill looks set to head to Chelsea instead of Old Trafford.
