Arsenal are taking a report striker Alexandre Lacazette inhaled nitrous oxide from a balloon “seriously”.
An article in the Daily Star showed the France striker pictured with a balloon in his mouth and he is said to have sent a video to friends.
An Arsenal spokesperson added that it was “a private matter” that would be “handled internally”.
Lacazette has previously been warned about a similar offence of inhaling the substance, also known as laughing gas. (Text, photo by BBC)
