Liverpool have reportedly refused to comment on claims that Raheem Sterling has again been inhaling laughing gas (nitrous oxide).
The England international was warned over his behaviour back in April after a video emerged of the 20-year-old taking the legal high from a balloon while with friends.
A fresh clip has been published by The Sun apparently showing Sterling and friends inhaling the gas at a party, but according to The Telegraph, the Merseyside outfit have chosen not to comment.
The alleged incident comes just one day after Manchester City reportedly lodged a £40m bid for the youngster after their initial £30m offer was rejected.
It is believed that the Reds will again rebuff the former Premier League champions as they are keen to keep Sterling, who has two years remaining on his contract.
