Jack Grealish is said to have been involved in a 'physical altercation' with Atletico Madrid defender Stefan Savic in the tunnel following Man City's progression to the UEFA Champions League semi-finals.
The incident occurred following a fiery game at the Wanda Metropolitano. Tempers boiled over at the end of the quarter-final second leg, with Felipe seeing red.
Grealish – an unused sub on the night – had had an altercation with Savic during the incident in which Felipe was sent off, with footage showing the the defender had pulled Grealish's hair on the touchline after the pair exchanged words.
The animosity between the two then continued after the full-time whistle, as BT Sport reported that the two were involved in a scuffle in the tunnel and eight police were tasked with intervening.
