Leeds United owner Massimo Cellino is attempting to spark a bidding war for the club.
The Daily Mail says there are concerns about the financial clout of interested party, Steve Parkin. Parkin, who owns non-league Guiseley, is worth an estimated £200million.
Soft drink giant Red Bull has ended any lingering interest in lodging a formal bid for the Whites after a social media frenzy at the back end of last season when members of staff were spotted at a game.
There were fears that Red Bull would change the name, badge and even location of the club and they were met with fierce disapproval.
Cellino is ready to leave Leeds amid supporter unrest and angered fans last week by dismissing their financial plans to purchase a controlling stake as "fairytales" after seemingly agreeing to dialogue with Leeds Fans United. He would not agree an exclusivity period with them and is actively inviting others to bid.
