Manchester United and England forward Mason Greenwood apologised and admitted to showing poor judgement after a video emerged online which shows him inhaling gas from a balloon.

British media reported that the video was filmed several weeks ago and shared on social media platform Snapchat.

The 18-year-old Greenwood was sent home from the England squad in Iceland last week along with Manchester City midfielder Phil Foden for breaching Covid-19 protocols.

“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 my part,” Greenwood said in a statement issued by United.

“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.”

Arsenal striker Alexandre Lacazette was investigated by his club this year following a similar incident and several Arsenal players were warned in December, 2018 for inhaling gas from balloons, believed to be nitrous oxide or “laughing gas”.

This season onwards, Greenwood will be wearing No. 11 shirt made famous by Manchester United legend Ryan Giggs and the latter heaped praise on the player.

The 18-year-old has already made more than 50 senior appearances for the Old Trafford side, scoring 17 goals and creating five more assists in the process.

The Wales boss does not believe that he will buckle under the pressure of wearing such a storied number.

“He’s nearly already scored more goals than I did, so there’s no pressure in that respect. I don’t think he’ll feel the pressure of the number,” The Sun quoted him as saying.
