Manchester United star Mason Greenwood has already learnt from his mistake.

Mason Greenwood has transgressed for the first time in his professional career and will be disciplined by Man United but also needs to be educated.

There was a startling story at the height of lockdown about a well-known English footballer hosting a house party but instructing their guests to leave phones outside to prevent any evidence surfacing. To this day, no pictures or videos have emerged from the gathering and no-one will ever know how many guests tested positive for COVID-19.

"Some think they are superhuman," an agent said at the time. The suspicion was some footballers only requested a COVID test so they could flout lockdown rules and there was disappointment at how few wanted to be proactive in offering support.

All footballers are not so selfish. There was a trend of younger professionals, usually aged around 16 or 17, contacting their advisors and eager to make a difference. In early April, twins Josh and Jacob Murphy ventured out to deliver prescriptions to elderly residents in Norfolk as part of Downham Market volunteer group.

Manchester United were one of the leading clubs when it came to a duty of care: 30,000 items of food and drink were donated to local charities, club medical and protective supplies were available to local hospitals, Old Trafford facilities were open to the NHS, 60,000 meals were delivered to NHS staff and £50,000 was donated to local food banks.

United were well within their rights to diplomatically express 'disappointment' at Mason Greenwood's behaviour in Reykjavik. Their statement was shorter and tamer than Manchester City's about Phil Foden but Greenwood should be braced for the Norwegian version of The Hairdryer Greenwood was always going to be tested before reentering Carrington but sources at United say they 'need to establish all the facts' before deciding when he should be summoned to their training fortress.
