Alexandre Lacazette's training-ground scuffle with Cedric has been uncovered by the latest All or Nothing: Arsenal clip.
Amazon film-makers were given access to film the Premier League side for a fly-on-the-wall documentary, with the final two episodes of the eight-part series released for streaming online on Tuesday.
And footage from the final episode shows an explosive training-ground bust-up between Lacazette and Cedric which saw the striker grab his team-mate's face.
Manager Mikel Arteta and players were forced to pile in to split up the pair's heated confrontation.
The scuffle was caused in an intense training session, when Lacazette challenged youth team player Jack Henry-Francis.
