bbc sports Michael Johnston has defended his belief that the Old Firm ought to favour a more even spread of money to create a more competitive league.
Rangers manager Walter Smith had made a barbed reply to the Kilmarnock chairman's comments on Friday.
Johnston said on Sunday: "It has long been my view that there is a disparity in the financial model and that it is loaded in favour of Rangers and Celtic.
"We could examine the distribution of revenues, principally TV contracts."
Speaking to BBC Radio Scotland ahead of Kilmarnock's Scottish Premier League match against Celtic, Johnston added: "I think Walter and I are in agreement, that there should be financial fair play in Europe.
"The same points he is making in relation to the distribution of Champions League finances could equally be argued in the SPL."
Smith had spoken about the inequality in football finance after Rangers' backs-to-the-wall performance earned the Ibrox side a goalless draw at Old Trafford, a defensive display that attracted both plaudits and criticism.
"Walter sees Rangers and Celtic as being the standard bearers for Scottish football in Europe," added Johnston, who described the veteran manager as "a fine fellow".
"But I don't think we should look upon that as something that should happen in perpetuity, which is perhaps the way the Old Firm approach it.
"They want to keep the status quo because it virtually guarantees that they will remain the standard bearers in Europe and we need to get back to the days when Aberdeen, Dundee United and the bigger clubs have an opportunity to compete at the highest levels.
"I think that could be helped if there is financial fair play in Scotland as well as in the rest of European football."
At Rangers' media conference on Friday, Smith made reference to the SPL's ill-fated broadcasting deal in 2008.
The Rangers manager asked: "Was the Kilmarnock chairman one of the people who agreed to the Setanta deal?
"I don't know if he was or he wasn't. But if he was, why is he still in a decision-making position in Scotland?
"They had the chance to get the money from Sky and they didn't take it. They took Setanta and it was the wrong move and it's cost them a fortune."
Johnston responded on Sunday, arguing: "There were sound reasons for going with Setanta rather than Sky. The SPL employed media consultants at great expense, who had no concerns about the Setanta TV contract.
"They also employed competition lawyers from London who did warn about going with Sky: it was feared that that would have led to a competition law challenge by Setanta.
"It's easy with hindsight to say that was the wrong decision, but back in the summer of 2008, nine clubs out of 12 decided that Setanta was the correct way to go.
"None of Rangers, Celtic nor Aberdeen put forward any objective argument at the time which was against Setanta and in favour of Sky.
"Not only were there no arguments put forward, there were no senior people from Rangers or Celtic who attended the decision-making meeting."
Describing the decision to abandon a 50-50 share of league gate receipts as "a huge step in the wrong direction for smaller clubs", Johnston called for a change to the way in which income from the SPL is distributed.
He believes that a more even spread of cash would create a more competitive and commercially attractive top league in Scotland.
"One of the things we could do now is examine the SPL distribution model for central revenues, principally the TV contract, but there are also other contracts with the BBC and overseas broadcasters," he said.
"The way the money is divided up within the SPL at the moment, 32% of that goes to the teams that finish first and second. Third place gets 9.5% and then it goes down fairly evenly after that.
"If there was more money going to the teams lower down the league it would give them the opportunity to strengthen.
"That might improve the competition, there would be less predictable results and it would be a better spectacle for the spectators.
"If the league is a better competition, then it should attract more money and everything would grow on the back of that."
But a change in cash distribution would require the backing of at least 11 SPL clubs.
Johnston is aware that the Old Firm would have to vote in favour of it, or split their vote, the result of which might one day be that their income from continental competition would dry up.
"More competition would put European qualification places in jeopardy for the teams that have the monopoly on them at the moment," was his blunt assessment.
