Manchester City have launched a fresh legal challenge against the Premier League’s sponsorship rules in the latest escalation of English football’s civil war.

Manchester City has registered another legal challenge against the Premier League over rules about “associated party transactions.” The British Press Association reported Friday that City is contesting amendments made to the APT rules voted by Premier League clubs last November.

City believe the new associated party transaction rules, voted through in November, face the same legal obstacles as the previous ones.
