The FA are reviewing an incident from Manchester City's 4-1 victory over Liverpool, as per The Mirror.
City midfielder Rodri fouled Reds attacker Cody Gakpo moments after the former had received a yellow card, sparking a number of Jurgen Klopp's squad surrounding referee Simon Hooper as urged the official to show the Spanish international a second yellow card.
Hooper ignored their claims and Rodri escaped a sending-off, although the Merseyside-based club may not be so lucky if the FA deem them to have breached FA rule E20.1, which involves players conducting themselves in an orderly fashion. Premier League leaders Arsenal were charged twice back in January after allegedly breaching the rule against Newcastle United in the league and Oxford United in the FA Cup.
