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.

The British Press Association reported Friday that City is contesting amendments made to the APT rules voted by Premier League clubs last November. Those changes were forced on the league by an earlier legal challenge by the defending champion.

The club’s bad season might get worse as it faces 115 charges of breaching financial rules. The fallout will reverberate beyond football.
