but how are you assessing "the best teams in Europe"? show me a list of the best teams in Europe 50, 40, 30 and 20 years ago. would they be the same teams? they would not. football moves in cycles, ups and downs. there is nothing wrong in clubs moving up the leagues and claiming a place in the top table of euro footy, and there is nothing wrong in letting a top team fall as low as they need to go to change their ways and become good again.
what is wrong is artificially elevating teams to a level above most other teams can reach, ever... no matter how shit they become.
to find the best teams, isnt that what leagues are for? to bring the best teams to the top... and isn't challenging other leagues best teams the just reward for winning your own league?
