This won't last long.
The thing is, the ground staff are all on minimum wage and just want to get home in one piece. Therefore they won't give a stuff about these rules, won't check anyone for any of this nonsense, and when it hits five mins before kick off they'll let everyone pile in anyway. Like always. And more power to them, because teenagers on minimum wage shouldn't have to stand in the freezing cold and deal with angry football fans over their failure to provide pointless documents that don't prevent the virus from spreading anyway.
The sheer size of the absolute chasm between the people in offices coming up with these rules and the minimum wage staff being asked to enforce them cannot be underestimated. Masks are once again being "required" in shops. So off I trot to Asda with my mask on. Not one member of staff was wearing a mask in the whole shop. For rules to be enforced properly you have to make sure that the staff want them to be enforced at all, which they don't. So good luck!
And neither do the public! Bars are still rammed, cinemas are still sold out, football stadiums are still packed, public transport is still full up at peak times, people still travelling round the world. People trust vaccines over behavioural restrictions, and rightly so. Our next home game is on Boxing Day. The stewards will probably have a "training day" beforehand where they'll be given the directive, so they'll make a show of it. Then we'll all go back in the new year and the staff will go back to simply waving us through.
