One of the biggest problems is the fact that, for example, there are several "elite" clubs in England nowadays who can obviously afford to pay top bucks for the best players, and everyone else is only making up the numbers.
So, as long as they keep letting several clubs from the same country enter, and there are others besides England, you will have champions from so-called lesser footballing nations at a massive disadvantage before a ball is even kicked.
It's as bad nowadays in England as it always has been in Scotland where only the Old Firm win the SPL.
Who else in England in the forseeable future outside of Man U, Liverpool, Chelsea and Arsenal can compete? Perhaps Man City now that they've got "oil money" but how long will that last?
