Manchester City's FA Cup final clash with Crystal Palace reached its boiling point after Daniel Munoz appeared to put the Eagles 2-0 up moments before the hour mark.
The wing back's goal was ruled out after Ismaila Sarr was adjudged to have been offside in the build up, which followed in a dugout frenzy less than a minute later.
City's head of sports medicine - Max Sala - came to blows with Palace's assistant manager - Paddy McCarthy - with the two standing within millimetres of each other as they exchanged words in a face-off.
