Thing is on my FB feed I have seen petitions for the arts, keeping gyms open, keeping pubs open and others in the past week alone. There is a huge amount of competition out there, apart from poor old cinemas that have nothing to show everyone else seems to be trying to pressure the government. Every other industry and group in leisure is after either financial support or the right to operate in lockdown conditions or both.
Without meaning to be pessimistic, I can't see fans in stadia in 2020 with the current situation as it is. I might be wrong, but I cannot see it happening.
