Former Manchester United boss Tommy Docherty has told Sir Alex Ferguson to forget about going for Arsenal striker Robin van Persie.

The Doc has urged United not to sign Arsenal contract rebel Van Persie.

Docherty, boss of United from 1972-77, said: "What right as a player does van Persie have to say Arsenal is not heading in the right direction?

"He might be looking to move, but I don't think United should touch him with a bargepole.''
