Mason Greenwood has apologised for his "poor judgement" after footage emerged of the Manchester United forward apparently inhaling laughing gas.
The 18-year-old appeared to breathe in nitrous oxide from a balloon in a video reportedly filmed a number of weeks ago.
The footage emerged in a national newspaper this weekend and is the second time in a week Greenwood has been the source of controversy, having been sent home from England duty last week after breaching Covid-19 guidelines, an incident for which he also had to apologise.
Greenwood has now urged others not to follow his example, with the teenager having since been told of the risks of nitrous oxide.
In a statement from United, Greenwood said: "I have now been made aware of the health risks associated with this practice and accept that even trying it, as shown in these historical pictures, was poor judgement on may part. I strongly urge others not to follow my example.
"As an 18-year-old I am learning all the time, however, this week I have also learned that I will be judged to a higher standard because of my career as a footballer and I must respect that in future.
"I am determined to repay the faith shown in me by my manager and coaches."
The pictures emerged just a week after Greenwood and Phil Foden were sent home from England duty after breaching Covid-19 rules.
