Ademola Lookman had to be held back during a furious row after being grabbed by his Atalanta manager Ivan Juric on Wednesday night.
The former Everton winger, 28, was substituted in the home Champions League game against Marseille that the Italian side went on to win 1-0.
And as Lookman came off the pitch, there was an exchange of words between him and Juric, seemingly about his annoyance at being brought off.
Juric then reacted and called back at his player, grabbing him at the same time before CEO Luca Percassi and team-mate Marten de Roon on the bench intervened to prevent the situation escalating further.
