Sir Alex Ferguson has said striker Wayne Rooney should stop doing promotional work for the Football Association when he is on England duty.
The Manchester United boss said 27-year-old Rooney was "too trusting" because the FA punished him "more than anyone else in the game" if he stepped out of line.
He told the Sunday Express he "wouldn't do a thing" for the FA and said: "I keep telling him he's too trusting.
"I told him: 'I don't know why you do things with the FA.' He does things every time he goes down there. He should not be doing anything with them.
"They've not helped him one bit. Every time he does anything [wrong], they punish him more than anyone in the game.
"He should be realising that. I wouldn't do a thing for the FA but they force him to do it."
But English football's governing body hit back at Ferguson's claims, with a spokesman denying that Rooney had fulfilled any more media engagements than any other member of Roy Hodgson's squads.
"Wayne has not undertaken any commercial PAs [personal appearances] for the FA in the past 12 months and has not fulfilled any more media obligations than other senior squad members,'' the spokesman said.
"As with all England players, we look to ensure that media activity whilst on England duty is sensibly managed.''
Last week, Ferguson denied that there was any rift between him and Rooney after leaving the forward on the bench for the Champions League defeat against Real Madrid at Old Trafford.
His decision not to start Rooney sparked speculation that the player could be on the move at the end of the season.
But Ferguson said he wanted to see Rooney staying at Old Trafford, adding: "There's no issue with his contract - when it has to be renegotiated it will be.
"We don't want players to leave. He'll definitely be here next season, there's no doubt about that."
