Granit Xhaka reportedly told a group of irate fans to "shut up" after they confronted the Arsenal midfielder following their 3-1 home defeat to Manchester United on Friday.
The Gunners were knocked out in the fourth round of the FA Cup as goals from Alexis Sanchez, Jesse Lingard and Anthony Martial ensured a comfortable win for the visitors.
Xhaka was attempting to drive home from the Emirates after the game when fans surrounded his car and heckled the former Borussia Monchengladbach player.
According to The Sun, the 26-year-old rolled down his window and told his side's supporters to "shut up", before driving out of the stadium.
Arsenal sit fifth in the Premier League table and have been eliminated from both domestic cups this season.
