Kyle Walker and Erling Haaland were involved in some unsavoury scenes after suffering a 1-0 defeat at Arsenal on sunday.
The pair were spotted furiously confronting Gunners’ set-piece coach Nicolas Jover, who previously worked at City, as they walked towards the tunnel at full-time.
Walker seemed to take issue with something that was said and confronted Jover, with Haaland backing him up and several people trying to get in between.
Emotions were running high after City suffered their third defeat in four games, conceding a late deflected effort from Gabriel Martinelli.
Defeat for City has left them in third place going into the international break, having been leapfrogged by Arsenal after they took all three points late on. Tottenham Hotspur also went above them after beating Luton Town 1-0 on Saturday.
