Surely if the Government says fans are allowed in, clubs will be allowed to do it, subject to having a Risk Assessment and all the required safety measures in place.
Capacity will be reduced, so presumably only some season ticket holders will get to each game, hopefully through a rota system of some sort with us knowing our games well in advance so we can plan accordingly.
It may not actually work financially for the club though, as no walk up or away fans will mean no income on the day other than limited car parking and possibly some catering or shop sales. The club is probably better off not having to pay stewards, turnstile operators etc until normal crowd levels are allowed. I wonder if they could go with volunteers for those roles, so a few more season ticket holders can get in?
