Unai Emery will speak today to a group of Arsenal's senior players who are alleged to have inhaled nitrous oxide at a pre-season party.
Stars including Mesut Ozil, Pierre-Emerick Aubameyang, Alexandre Lacazette and Matteo Guendouzi feature in the footage, which appears to come from nightclub CCTV footage and was published by The Sun.
Arsenal Football Club will warn all the players involved in the wild party using "hippy crack" before the start of last season.
The footage is the latest to show top players being linked with nitrous oxide.
After seeing the video, an Arsenal spokesperson told BBC Sport that players would be "spoken to and reminded of their responsibilities".
Henrikh Mkhitaryan and Shkodran Mustafi have also been identified in the video, but neither were seen inhaling the gas, with Mkhitaryan actively refusing to be given a balloon.
Nitrous oxide, also known as laughing gas or "hippy crack", is freely available, but it is technically illegal to sell it for recreational purposes.
Other well-known Premier League players have previously caused outrage after being filmed apparently inhaling the gas, including England internationals Kyle Walker and Raheem Sterling.
It can make users feel euphoric and relaxed, with some reporting hallucinations, and can lead to loss of blood pressure, fainting and even heart attack.
