Kevin de Bruyne shoved Arsenal manager Mikel Arteta after the Spaniard kicked the ball away from him during their Premier League clash on Wednesday evening.
De Bruyne was looking to take a quick throw-in during Manchester City's 3-1 win over Arsenal but the Gunners boss - and his former coach - blocked him from the ball and flicked it away.
In response, the Belgian shoved the 40-year-old Spaniard in the chest before running off to collect the ball.
After picking it up, De Bruyne exchanged words with the Arteta on his way back to the pitch and pointed his finger at the Arsenal manager before getting back to it.
