To be serious, its down to advertising, if more people watch UTD (be fans or not) then that.s whats put on TV, so will always have RM abd Barca on sky sports week in week out, because the money they command from the advertisers. Think a Stove v Wigan game will not command big advertising rate but UTD v Liverpool will command top doller.
It does raise the question of why so few people watched Chelsea last season. P'raps the anti-Benitez campaign extended to TV as well? They've usually been behind us in terms of fans watching games, but generally on a par with Arsenal and Spurs.
Its because of man united the premier league can sell the tv rights for so much. other clubs should be thanking us not moaning about how much we are shown. maybe be should be able to sell our own tv rights they might appreciate us then
