Sir Alex Ferguson has accused the FA of bullying referee Lee Mason into citing Wayne Rooney for swearing.
Manchester United boss Fergie claimed the FA put Mason under intolerable pressure to admit he would have sent Rooney off had he seen the striker swear into a camera after completing a hat-trick at West Ham last weekend.
Rooney will begin a two-match ban tomorrow after losing his appeal against his punishment having admitted a charge of using foul and abusive language.
But Fergie claimed there was a clear FA agenda against United because of their high profile.
"I don't think fair is a word we can use anymore [with regard to the FA]," said Fergie.
"We put an appeal in, Wayne wrote his apology for swearing, but obviously I don't think we expected to get a result to be honest.
"The person I feel sorry for is Lee Mason [referee] because he's put himself in a terrible position. Obviously he was put under pressure. There's no doubt about that. It's hard to believe a ref would send a player off for scoring a hat-trick.
"But he's now put himself in the spotlight and if he doesn't send a player off for swearing then the question will be: has he got double standards? It's a really difficult position for the lad and I feel for him, I really do."
Fergie also had a pop at Superintendent Mark Payne, responsible for managing crime response in Wolverhampton, who said Rooney would have been arrested and locked up had he sworn on his patch on a Saturday night.
"There is an issue in the modern world of a need to be noticed," said Fergie.
"There's a wee guy [police chief] sat down in the Midlands, probably never been recognised in his life, managed to elevate himself to whatever he is in the police force.
"Have you ever seen Birmingham on a Saturday night? Do the police there actually arrest people for swearing on a Saturday night? Dearie me. That's a good one isn't it?
"Anyway. We're disappointed about it, but we'll be united about it. We have to get on with it. We will face the problem because we've got a fantastic squad who have shown great determination recently.
"We're going to be hard to beat, that's for sure. I think it will bring everyone [at United] together. That's the great advantage, the great plus."
