The Red Devils may currently be sitting at the top of the Premier League table for the first time in three seasons, but lamenting the state of the English game, Collymore believes sleeping giants Leeds would add to the mix in the top flight.
Leeds remain one of the best supported clubs outside the Premier League, arguably the best, but are still paying the price for years of financial mismanagement, stranded in the Championship.
Collymore told his listeners: "Manchester United fans still sing about Leeds United. The self proclaimed greatest club, they see the value of playing Leeds."
His comments came as part of a debate about the need for big, well supported clubs from outside London, to be given a fairer slice of the financial pie, warning the current set up will further develop the gap between the have's and the have not's.
Collymore had called for the Premier League to be split into two divisions of 18 teams, with financial parity the goal, and allowing teams who win promotion to the top flight a better chance of success upon getting there.
Leeds, who finished 15th in the Championship last season, share a long standing rivalry with United - and frequently got the better of their rivals.
To that end there may be Manchester United fans who do not miss the prospect of dropping points at Elland Road, but for passion, atmosphere, and occasion, when the two clubs were at their peak there were few matches in English football which were bigger, and match going fans of both sides will surely yearn for those days to come again regularly, however it happens.
