Bates sold Chelsea to Roman Abramovich.
"Watching Leeds play Chelsea at Elland Road will be like getting a new Bentley with your mother-in-law in the passenger seat and watching it go over a cliff," he told the Daily Mail. "But it's a huge game for Leeds and I want them to win, of course I do."
He does, however, admit to being tempted to visit Rafa Benitez's players in their hotel this afternoon. They will be just across the road from his apartment, in the Malmaison.
"I only know a few of the players because so much has changed since I left, but it would be nice to see Frank and JT again," he said.
"It will be a fantastic occasion. We are playing the best team in Europe and the second best team in the world. Elland Road will be filled to the roof."
