"It was an interesting comment, I think it's a fan's-type comment," Gill told BBC Radio.
"It's interesting that when Sir Alex Ferguson mentioned the Dimitar Berbatov signing in advance, complaints were made to the Premier League.
"He mentioned Fernando Torres and Cesc Fabregas in the same article so I think we'll treat that with a pinch of salt.
"I've never met the gentleman. That's a fantastic amount of money and would turn the industry upside down so I can't believe he's serious at those sorts of levels.
"Ultimately we'd discuss any offer with Alex and the owners, as that sort of money is very large for one person. But we aren't in the market to sell our best players."
