Fans want to watch games, especially ones they have already paid for in their season tickets. Clubs do not want to play games behind closed doors, that is like Asda opening the shops but not operating the tills, they will go broke if they have no walk up gate receipts. Playing behind closed doors still involves up to 100 people risking infection. Playing behind closed doors still involves travelling and overnight stays in hotels or flights Playing behind closed doors still puts pressure on medical services/staff when they are needed elsewhere
Playing behind closed doors is not a good option for anyone.
