The government will announce which tier of restriction will be implemented on which region in England.
Fans can return to English football stadiums next week, ending an eight-month absence due to Covid-19 restrictions, but while the government's decision to open the turnstiles has been welcomed it also presents a series of new headaches for clubs.
The first hurdle clubs must clear will come on Thursday when the government announces which tiers of restrictions given regions in England will be placed in.
Clubs that fall into tier three areas, which contains the strictest restrictions, will still not be allowed to let any fans into their grounds.
Maximum of 4,000 fans
Only those in the lowest risk, tier one, region will be allowed to have the maximum of 4,000 fans while the middle-ranked tier two areas will be restricted to up to 2,000 fans.
"So some clubs will have fans backing them in home fixtures and others will have empty stadiums with no fans! Unfair competition or not??" asked former Manchester United captain Gary Neville, who is co-owner of League Two (fourth division) Salford City.
Even those clubs that are allowed to have fans in stadiums from Wednesday December 2, will need to have ensured that local safety advisory groups have been consulted and given the go-ahead.
Clubs would also have to bring stadium staff, including safety officers, some of whom may have been furloughed, legally back to work in time for the games.
Oxford United, who play in League One, English football's third division, expect to be in tier two, meaning they could have 2,000 fans in their 12,500 capacity Kassam Stadium.
But club managing director Niall McWilliams said that might not be possible right away.
"A few weeks ago we submitted plans for a trial game with 1,000 fans allowed in the ground and it may be that we have to be patient just a little longer and trial it with that plan and then step up to a larger number for the next game and hopefully keep building from there," he told the club's website.
Then there is the thorny issue for clubs of who will be the lucky fans who will be allowed to attend games and which loyal season-ticket holders will still be kept out and stuck at home.
Prioritising longtime season-ticket holders
Clubs will be wary of the potential for a backlash if they give priority to high-paying corporate customers and the danger of long-term supporters feeling snubbed.
Premier League club Chelsea said they were working on plans to "accommodate as many fans as possible, as fairly as possible."
Tony Stewart, chairperson of Championship club Rotherham United, said, “We’ll have to create some form of lottery and prioritise our longtime season-ticket holders, that’s what we’re looking at now."
As soon as the tiers are confirmed, clubs will have to quickly begin making plans and EFL chairperson Rick Parry suggested they might not be as ready as may have been expected.
"We weren’t really expecting anything before Christmas. There’s a lot of work to do quite quickly and it’s really important that we get this right.
It’s not a case of rushing into this and tripping over. It’s a case of being measured, getting it right," he said.
