West Ham United forward Marko Arnautović appeared to tell a fan to “shut the f*** up” after he was booed off the pitch during the 0-2 defeat to Everton.
The Austrian was substituted off for Grady Diangana after 67 minutes of Saturday’s Premier League fixture at the London Stadium.
His removal was greeted with jeers from sections of the home support who have grown frustrated with his lacklustre recent performances.
They were also resentful of his apparent attempts to engineer a lucrative move to China in January.
As he takes his seat in the stands in between team-mates Fabián Balbuena and Mark Noble, he hears a shout from behind him.
He swivels round and seems to deliver an expletive-punctuated instruction for the fan to be quiet, if his mouth movements are anything to go by.
Goals from Kurt Zouma and Bernard handed Everton a win that took them above West Ham in the table.
