John Ryan, the Doncaster Rovers chairman, has criticised people from his town who follow Leeds United ahead of Friday night's game against their Yorkshire rivals.
Leeds have traditionally attracted support from across their county - and indeed, North Lincolnshire - as they competed for honours.
The Whites fell from their former glories down to League One, placing them below clubs like Doncaster and Scunthorpe in the league pyramid.
"All these people who pretend to support Leeds and come from Doncaster, it's quite unbelievable," said Ryan.
"If you are from Doncaster you should support Doncaster Rovers We're better than Leeds anyway! I'm sure it will be a tremendous atmosphere inside the Keepmoat Stadium."
James Vaughan, the Everton striker on loan at Crystal Palace, would be happy to extend his loan spell beyond January. He scored a hat-trick on his debut as the Eagles defeated Portsmouth 4-1 on Saturday.

"I was pushing to come out and play some games, I got my wish, and at the moment it's paying off. I just want to push on from here and get some more games under my belt."
