I love how they're all acting like we didn't have a game postponed last season because Arsenal had four players out with it. And as it was then, yes in theory having four players out from covid shouldn't be different to any other injury or sickness, but this one risks passing it on to other players, so it should only be played when it's safe to do so.
I don't really know enough about how the science of testing for it works, but my assumption would be that if someone catches the virus, it doesn't show up instantly on a test, and so that's why the decision to postpone the game was taken so late. If new cases are discovered a couple of days before a game, then there's time to test people and for those tests to be accurate. Can anyone confirm or deny this?
