Manchester United boss Sir Alex Ferguson is adamant Manchester City's opening goal in last night's derby defeat should not have stood.
James Milner's piledriver arrowed into the net from 20 yards but Ferguson insisted Carlos Tevez should have been ruled offside.
Ferguson said: "The first goal, the player [Tevez] is right in front of David de Gea.
"There is no way the linesman on that side is giving it but if that is not interference I don't know what is."
