If anyone is worried about covid, I’d suggest a football stadium with 30,000 fans isn’t the place for you.
Depends. Individuals can still take precautions by not hanging about on the concourses, using anti-bac and generally being aware of their own surroundings and respectful of other fans. So it would still help if most people are vaguely sensible rather than 'tearing the pants out of it', to coin a phrase.
