Saddlers have bid to host a pilot at the Banks’s Stadium for 1,000 fans later this month as they await approval from the EFL.
Clarke, who has openly admitted to missing the fans, believes clubs like Walsall will struggle to survive if spectators are not allowed back through the gates.
“The game is not the same without the fans, without the passion and the drive,” Clarke said.
“We want our fans in as safely as possible and as quickly as possible, not just for the atmosphere and their support but also for the financial situation.
“Clubs can’t continue if we can’t get fans, I’m afraid, it’s not financially viable.
“We’re certainly not a club with a pot of gold at the end of it, we live within our means and spend within our means.
“It’s a proper, well-run football club but we can’t continue on a long-term basis without fans coming in.
“It won’t make sense.”
