Finance guru, Dr Dan Plumley, claims Sunderland may have to wait until they're promoted out of League One to see the back of Madrox.
The shocking revelation that Stewart Donald, Juan Sartori and Charlie Methven still own 59 per cent of the club, was the news every Sunderland fan dreaded.
It meant that Kyril Louis-Dreyfus' controlling share in the club only amounted to a disappointing 41 per cent, with fans lead to believe he owned a majority share.

While the Frenchman may indeed own the largest share in the club, the fact it's taken over a year for this to be revealed, has seen the Black Cats faithful lose trust in their new owner.
Sunderland CEO Steve Davison remains hopeful that Louis-Dreyfus can indeed buy Madrox out of the club, Dr Plumley believes their decision to keep shares makes sense from a financial point of view.
“It makes sense that they are keeping shares," he told Football Insider.
“Every owner has got their motives as to why they want to invest and when they ultimately want to sell.
“You only have to look at the crowds and infrastructure at Sunderland to see the appeal and growth potential there.
“If you’re an owner who is gearing up for a bigger sale further down the line, you can see why they wouldn’t want to sell up yet.
“You’d look to stay involved at least until you’re in the Championship or potentially even the Premier League.”
But for Sunderland fans, that sets a dangerous precedent.
Donald told Sunderland fans he would leave the club when he was not wanted, and yet, over a year later, he still remains involved.
The trio of Sartori, Donald and Methven still have to sign off financial decisions at the club, which has led many red and white supporters to question, once again, who has the final say at the Stadium of Light.
