I hope the government don't approach it as a country as a whole. For example, there's no way fans in tier 3/very high risk areas should be allowed in (North West/Notts) but those in medium risk areas should be where clubs can demonstrate they can get fans into grounds safely and socially distanced throughout the games should be.
Also, grounds where you need to take public transport to may not be allowed I think, out of town grounds where people can drive directly to themselves will probably be allowed fans in in my opinion.
We're in a medium risk area (the lowest tier), we're out of town and have 4 massive gates where fans can be admitted with the the hand held barcode scanners and walk down the side of the pitch to their seats. It's very doable at OUFC I think.
