Manchester City have been found guilty of the vast majority of 115 charges brought forward by the Premier League. The club were accused of a wide range of rule breaches, including inflating sponsorship revenue from connected companies and making "off the books" payments to circumvent football's financial rules. Purslow, who also held a senior role at Chelsea, said the case could begin a chain of events that would be "appalling for the game".
Premier League clubs are seeking legal advice about compensation relating to the charges, while BBC Sport has been told that City will appeal. Sanctions on the club are yet to be announced, but repercussions could include a points deduction, expulsion from the Premier League or a huge fine. Speaking on Radio 4's Today programme, Purslow appeared alongside football law expert Paul Gilroy KC, who described the case as a "seismic moment for world football".
