Lord Mawhinney, the outgoing chairman of the Football League, believes a salary cap is inevitable among the league's member clubs.
Mawhinney insists the current football financial model is not sustainable and has campaigned for the introduction of a salary cap in an attempt to halt the game's spiralling debt.
He told the BBC's Late Kick Off programme: "The business model of professional football in this country doesn't work, it's broke and you see that reflected in the administrations and all the rest of it.
"I have some clubs in the Football League who are paying up to 85% of their income in wages.
"I don't care how great you are, you may be the best business entrepreneur the country has ever come up with, but you cannot run a sustainable business with that sort of model.
"I think I have given the issues a reasonable profile and I think even those who don't approve of me would probably concede that.
"Our Championship clubs in particular are not yet ready to commit, but it'll happen because what is going on presently is not sustainable in the medium term."
Earlier this week the Football League appointed Greg Clarke, the former chief executive of Cable and Wireless Communications, to succeed Mawhinney.
