Glasgow clubs Celtic and Rangers have both expressed their desire to join a European League with teams from Holland, Portugal and Scandinavia although UEFA, soccer’s ruling body in Europe, will block any such move.
But, as French player Zinedine Zidane broke the world record transfer fee by moving to Spanish club Real Madrid from Italian side Juventus for a reported $67million-plus, Mitchell admits that the Scottish game will never compete with the world's best.
"The way commercialisation in football is going, you will get something commensurate with the size of your market," said Mitchell.
"That means we will always get one-tenth of the money that they get in England - from sponsorship or television.
"That means that they will always have ten times more gunpowder to attract talent and that is a problem for small leagues like Holland, Portugal and ourselves.
"This is a problem for us being in a small market and football rules not allowing us to do what any other business would do to grow, which is move into a mixed market.
"We cannot move beyond our boundaries because football is based on a geographical basis.
"That is why our organisation and the bank was flexible with the Euro League, if it was done under certain principles which would benefit all the clubs.
"We are flexible to British solutions but what we are not going to do is sit here and say this is it and what we have to be consigned to.
"We all have to try and earn a salary a bit better than that. That is the problem for football - it is concentrated in five big countries.
"The juxtaposition is interesting because you get clubs like Clydebank, Morton and Airdrie on the same page as $67m for Zinedine Zidane.
"The issue about where football is going is an important one and you can only do it with the people who provide finances.
"The Euro League wasn't Celtic and Rangers leaving - it was an amalgamation of the Dutch, Portuguese and Scottish leagues."
Mitchell added: "Celtic are a plc and they have an obligation to their shareholders.
"We do pretty well commercially with the market we have but it is frustrating for all of us.
"It is frustrating for other SPL clubs to see that they can't compete easily with English clubs and the Nationwide League. Everybody understands where it is coming from."
The head of Scottish soccer’s Premier League, chief executive Roger Mitchell, has called for changes to the hierarchy of the game.
