Tottenham boss Antonio Conte and Arsenal midfielder Granit Xhaka got into argument during the north London derby as tempers flared.
Arsenal raced into a two-goal lead in the first-half after an own goal from Hugo Lloris and a fine long-range strike from Martin Odegaard.
And the match turned feisty in the second-half when Cristian Romero went flying in with a slide tackle on Xhaka, appearing to narrowly miss him.
But the Swiss midfielder went down clutching his ankle, alerting referee Craig Pawson, who took no further action against Romero, who ran the risk of being sent off having earlier received a yellow.
Conte was furious at Xhaka’s calls for further punishment and screamed at the 30-year-old, who is no shrinking violet himself.
Even Mikel Arteta looked like he was ready to get involved before he was calmed down by a member of his coaching staff.
Tempers frayed at full time with a Tottenham fan seen kicking Gunners goalkeeper Aaron Ramsdale from the stands after Ramsdale and Richarlison had a heated exchange.
Arsenal’s win sees them go eight points clear at the top of the Premier League.
