With Wednesday entering administration on 24 October, the Owls will be on the market for 28 days, until at least 21 November, under EFL rules.
But Wigfield has thanked the club’s supporters for their show of loyalty in buying match tickets and merchandise from the club shop to help with day-to-day running costs.
“This also has a secondary effect of clearly demonstrating to prospective buyers the huge potential of this historic club,” he added.
At this stage, Wigfield said that potential buyers have to provide proof of funds of £50m to cover the club’s liquid assets before they will be allowed to study Wednesday’s financial figures.
He added that the market will dictate at what price the club is valued, while any buyer would have to pass the EFL’s Fit and Proper test and also have proof of funds for two years after purchase.
