Former Manchester City colleagues Kevin de Bruyne and Mikel Arteta were involved in a touchline fracas during City's 3-1 win over Arsenal.
The pair spent three-and-a-half-years working together between 2016 and 2019 while the now Arsenal manager was an assistant coach in Pep Guardiola's City backroom staff. Arteta arrived a year after De Bruyne returned to the Premier League, and together they won two titles and an FA Cup, as well as two Carabao Cups.
Prior to the incident, the Belgium international had scored the opening goal of the game with a fine looping finish before Bukayo Saka equalised for the hosts from the penalty spot before half-time. The scoreline remained 1-1 when the two came together just over five minutes into the first half.
