Manchester United supporters fear Mr Rupert Murdoch's proposed takeover at Old Trafford has little to do with an interest in football.
United fans say he is not the man for Old Trafford and are likely to make their feelings known at tomorrow's home match against Charlton.
Mr Lee Hodgkiss, spokesman for the Independent Manchester United Supporters' Association, said: "We are very disappointed at the news. There is bound to be a reaction from the crowd during the Charlton game and the atmosphere should be fairly tense.
"If Manchester United is to be sold then we would rather it were to someone with a genuine interest in football. I'm pretty sure that Rupert Murdoch doesn't fall into that category."
The Football Association meanwhile has told Manchester United to talk to the fans before agreeing to any deal with Mr Murdoch's BSkyB.
The FA chief executive, Mr Graham Kelly, said: "We understand the matter is to be considered by the Office of Fair Trading, which we would expect. We are anxious to discuss this with the government.
"There is a responsibility of those concerned with such deals to explain them to the wider football audience, not least their own supporters. We have to assess the implications very closely indeed."
The chairman of the FA, Keith Wiseman, also insisted that the organisation would be anxious to make sure there was no conflict of interest in BSkyB owning Manchester United as well as owning the Premiership's television rights.
"We would hopefully be able to control areas like that which are specifically football areas but not necessarily the transaction itself," he said.
Manchester United yesterday announced plans to extend Old Trafford by 12,400 seats, taking its capacity to 67,400, while its manager, Mr Alex Ferguson, insisted he had known nothing about BSkyB's talks with the club.
Mr Ferguson acknowledged the talks had worried fans but told the Manchester Evening News: "Our supporters know full well that I have always considered them to be a major part of this club."
The former Manchester United director Mr Michael Knighton believes Mr Murdoch would be getting the club "on the cheap" if his BSkyB company succeeded with a £575 million takeover bid.
"I believe the case needs to be considered very carefully as it has major repercussions for football," he said.
