Ben Chilwell and Thiago Silva were spotted having a heated discussion during Chelsea's first half capitulation at Arsenal.
Goals from Martin Odegaard and Gabriel Jesus saw the title chasers race into a three-goal first half lead, with Frank Lampard's side left to lick their wounds once again.
Arsenal looked to be heading back to the summit of the Premier League table as a result of their sparkling attacking efforts as Chelsea continue to be forced to look downwards.
Following Odegaard's second of the night, Chilwell and Silva were spotted engaging in what looked to be a blazing row about defensive positioning and other factors which led to Arsenal doubling their lead.
