Until theres a vaccine, which lets be honest will probably be another 6 months away (and thats generous considering we didnt even develop one for SARS), any form of entertaiment wether thats sport or a music venue will be irresponsible to open.

Perhaps advances in near instant covid tests will help, as in theory you could do tests before entering a venue might help, but not sure thats possible currently.

Watching the Bundesliga with empty stadiums felt a bit like watching a kickaround at GOALs. Frankly no sport should even consider returning until the new year. Scrap all cup competitions, and a compact season between Jan-May could be possible, but even then thats wishful thinking. Putting profits before lives is fairly poor, plus lets face it who wants to go to a half empty stadium, 2 meters apart from everyone wearing face masks?
