Former Leyton Orient owner Barry Hearn concedes he made a mistake in selling the stricken club to Francesco Becchetti and has called on the Italian to sell up.
Hearn still retains the honorary presidency of the club he owned for 19 years but he has no day-to-day involvement and has watched the O's endure a torrid season of managerial departures, imminent relegation from the Football League, an adjourned winding up order and unpaid players.
Speaking to BBC Radio Five Live's Sportsweek, he said: "Sadly, I sold to the wrong person.
"Everybody, including myself, thought it was wonderful, hoping to go to the next level with the investment these billionaires bring.
"Mr Becchetti hasn't let anyone down with the amount of money he's put in. What nobody could have envisaged or foreseen was the inordinately terrible management decisions and involvement Mr Becchetti has had. Ten managers in three seasons is unthinkable.
"The fact wages of both players and employees have not been paid...these people have mortgages, bills, children...that is where my tolerance of the fact Becchetti has ownership has moved to another level.

"That level is: this man has to go. If this is how he treats people he has to go."
Hearn, who is 69 years old and chairman of World Snooker, has distanced himself from retaking control of Orient but said he would offer "background" assistance to any interested parties.
