Nuno Tavares of Arsenal appeared to ridicule Joao Felix after the recently signed Chelsea player was sent off in his debut Premier League game for the Blues on Thursday.
The loanee from Atletico Madrid had a dreadful start to his career. Tavares, who is on loan from Arsenal to Marseille, appears to have made a joke about Felix.
Chelsea eventually lost the game despite goals from former players Willian and Vinicius. For the visitors, Kalidou Koulibaly drew one back.
He tweeted: “Joao Felix. What a player anyway.”
