The most sensible suggestion (above all political posturing) I've heard so far is the potential rotation of seats for season ticket holders. I would rather watch half of the seasons home games rather than none. I think this is easily achievable with some form of social distancing model implemented. Stewards on the toilets pre match and half time, to ensure a set amount of people using them. Close the food kiosks.
Stewards on the toilets - what a nasty image.
