Didi Hamann believes fans of Liverpool and Manchester United could boycott games in order to stop their clubs' participation in the proposed Super League.
"I don't think this will go ahead," Hamann said on Eamon Dunphy's podcast, The Stand.
"If fans are allowed back in the next few weeks, I wouldn't be surprised if the Liverpool fans or United fans don't take up their tickets.
"I think they could play behind closed doors for longer than they think, but not because of the pandemic but because of their behaviour, and people don't put up with it."
Hamann believes the Super League - what he called both "hideous" and "greedy" - is simply short-term thinking by clubs like Real Madrid who are deeply in debt.
"It's a last throw of the dice for these clubs who've been hugely deficient in the last decade in getting their books in order," said the former Liverpool player.
He also feels that Liverpool being one of the league's founders is another sign that their American owners do not understand the club.
"The foundation that Bill Shankly laid 50 or 60 years ago gets torn down within days and weeks [if the Super League goes ahead]," said Hamann.
"The other thing that strikes me with Liverpool is that they tried to hike up the ticket prices two or three years ago, then they furloughed staff about 12 months ago, and now they want to join a European Super League which basically makes a mockery of the Premier League.
"They've been there for a decade. The sad thing about this, these guys do say the right things, but they don't act accordingly. You've got to say that to this day, they have not understood the football club.
"You've got a situation where the fans ask for banners to be taken down in the Kop. I just worry that it puts a divide between the team and the fans because this was always something which Liverpool thrived on and was a huge part of their success in the past."
