Emiliano Martinez had to be physically restrained following Aston Villa's comprehensive 4-1 loss to Arsenal on Tuesday evening after home supporters taunted him in the tunnel.
Fan footage captured the 33-year-old goalkeeper reacting furiously to goading from Arsenal fans as he made his way down the tunnel at full-time.
The Argentine initially appeared to brush off the provocation with a smile before seemingly preparing to confront the supporters directly.
One fan could be heard shouting: "You're not dancing now are you?"
Martinez, known for his provocative celebrations, was pulled away before the situation could escalate further at his former club.
The World Cup winner endured a difficult night between the posts, particularly for Arsenal's opener when Gabriel Magalhaes dominated him at a corner before he failed to collect the ball.
Martin Zubimendi doubled the hosts' advantage, with Leandro Trossard and Gabriel Jesus completing the rout before Ollie Watkins netted a late consolation for the visitors in stoppage time.

The heavy defeat brought an abrupt end to Villa's remarkable run of 11 consecutive victories, with the typically combative goalkeeper unable to prevent the collapse at the Emirates.
Martinez could do little to stop the subsequent goals after his shaky start to proceedings.
Following the match, the Argentina international took to social media but chose not to address the confrontation with supporters.
