Yes and for quarantine to work, she will be required to quarantine too. So is she being kept away from her kids for 3+ months while this goes on? How about he chefs employed to cook meals? The people who send the ingredients? Are they all quarantining? Not to mention the multitude of presenters, reproachers, journalists, editors, producers, directors, cameramen, runners, lightning engineers etc that exist around the game who don't play it.
You also have then the police, stewards, paramedics, ambulance drivers, doctors etc who are on call at every game (as a legal requirement). So do they all have to go into quarantine as well?
Unless you want to quarantine all of the people, and get them all to agree to 3 months away from the family, you are risking it spreading. And believe me, in that close proximity, the moment one person gets it will spread like wildfire as it did the last time the PL tried to insist on playing games, against all advice.
It would be a farce to try and insist upon it, at a time of national disaster and people would rightly, never forgive the selfishness of football.
People have to get through their heads, a group of healthy 20 something men and an industry that chooses to pay them millions of pounds a year, is essentially wholly irrelevant in the wider discussion of what is a priority for this country.
If we have 92+ hotels with training facilities (we don't) but even if we did, we should be giving them to homeless people, women fleeing domestic violence and NHS staff needing to self isolate.
