Disgusting. Matches without fans kill the atmosphere of football and turn even the most important match into a simple training session.
By the way, is this justified? It seems that the new strain of the virus has a negligible lethality, that is, it is very similar to the usual flu. Flu epidemics happen every season, but no one is imposing such a crackdown because of it.
You are right, but there are simply too few alternatives. Think it will continue with or without supporters for the time being. The commercial money is too big and has too much influence. Clubs have contracts with sponsors and media companies, so they can't just say they don't want to play anymore. Interests are way too big. Intermediate solutions could exist, with partial public but difficult to maintain.
What specific alternatives are you talking about? What are the specific intermediate solutions? At least I see a great illogicality in the fact that the authorities claim that vaccines allegedly work, but restrictions are imposed on absolutely everyone - both vaccinated and unvaccinated. Why can't I go to a match of my favorite team if I am fully vaccinated?
