Celtic and Rangers could reportedly quit the SPFL in order to join a new league featuring top teams from across Northern Europe.
The so-called 'Atlantic League' would feature 12 to 16 teams from Scotland, Denmark, Belgium, the Netherlands, Norway and Sweden competing in the equivalent of a domestic league structure.
The new competition has been proposed amid mooted changes to the Champions League that will see big clubs from the likes of England, Spain and Italy given an easier route into the European showpiece at the expense of sides from smaller footballing nations.
Asked about the Atlantic League in an interview with Danish newspaper BT, FC Copenhagen director Anders Horsholt said: "Yes, it's true. If we do not act now, we will see the biggest clubs grow larger and stronger while it will be increasingly difficult for clubs like us.
"We must therefore look at alternative international opportunities for FC Copenhagen in the future. Here it is still too early to talk about specific models, but the discussion of leagues across European borders is a theme that we look at and actively participate in.
"FC Copenhagen and other European clubs that will be part of a new European league will step out of their domestic leagues. It is still well in the future, but it may well be the result."
The clubs are thought to have been in discussions over the idea for the last three months.
