The Chelsea Supporters' Trust have written to Premier League chief executive Richard Masters, calling on him to use his power to investigate and act on Todd Boehly's connection to controversial ticket sale website Vivid Seats.
The CST write they have contacted Boehly directly to offer the American billionaire 'multiple opportunities to both publicly and privately address supporters' concerns' but that their requests have been in vain.
They add their members are 'infuriated' that their co-owner is involved in a website used to flog tickets to Premier League fixtures, including his own team's.
