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.
An Arsenal spokesperson told the BBC players would be "spoken to and reminded of their responsibilities".
After apparent footage of the Arsenal players inhaling the laughing gas emerged recently, the London club released a brief statement addressing the situation.
Gunners stars Henrikh Mkhitaryan, 29, and Shkodran Mustafi, 26, are also apparently in the footage but are not seen with the balloons. It is not illegal to possess nitrous oxide but it is illegal to supply it under the 2016 Psychoactive Substances Act.
Some of the players reportedly collapsed and passed out after inhaling the gas.
The incident took place in August, just before the start of the season, when a number of the London club's squad members enjoyed a night out at Tape Club.
Nitrous oxide is legal and normally used in dentist's offices and hospitals.
The Arsenal marksman is in scintillating form this season, leading the Premier League scoring charts with 10 goals.
Arsenal, under new manager Unai Emery, are now fifth in the Premier League table and are unbeaten in 20 consecutive matches in all competitions.
