Patrick van Aanholt has mocked Arsenal outcast Matteo Guendouzi on Twitter after the pair clashed in the Europa League.
Guendouzi has already rubbed several team-mates up the wrong way since joining Marseille on a season-long loan in July.
Galatasaray left back Van Aanholt was the latest player wound up by the 22-year-old after the midfielder went down under a challenge from the Dutchman in the box deep into the second half and was given a penalty.
However, the decision was overturned after VAR got involved and the pair had to be separated following the goalless draw by team-mates and backroom staff.
