Manchester United are lining up a shock raid for Manchester City defender Micah Richards.

The Mirror says the City hierarchy have become increasingly concerned by the defender’s erratic performances.

City staff also have worries over the attitude of the former England starlet, who has 12 caps.

And if City decide to offload the versatile defender, then United are ready to bid for him.

Old Trafford boss Sir Alex Ferguson is a huge admirer of Richards and tried to sign him when he first broke on the scene.

Ferguson is considering his options at right-back with growing concerns about Gary Neville’s fitness and Rafael Da Silva’s ability.

Ferguson believes his strict man-management could control Richards and United are hoping to do business if City will sell to them.
