The United boss shifted his midfield shape for the Capital One Cup victory over Newcastle, and his side repeated this victory in the Premier League on Sunday. A 2-1 Champions League win in Romania against CFR Cluj was also achieved utilising the same option. The new-look midfield diamond consists of Michael Carrick at the base, Shinji Kagawa and Tom Cleverley switching between the left and right points, and Wayne Rooney functioning behind two front men. Ferguson believes that although it was a risk to change things so early in the season, it is a gamble that is already showing clear evidence of paying off.
"We took a gamble because Newcastle are good crossers of the ball," Ferguson said in The Sun.
"But the football we played from the central midfield positions through Cleverley, Kagawa, Rooney and Carrick was terrific.
"People look at the name Cluj and say they expect United to win but they are a decent side.
"Because we played so well I thought we should find out how far we can go with that system."
United now sit second in the Premier League, four points behind leaders Chelsea.
