3rd Tier- As in:
1st Tier Leagues in Europe: Spain, England, Germany, Italy, France
2nd Tier: Russia, Portugal, Ukraine, Turkey, Netherlands
3rd Tier: Greece, Croatia, Belgium, Czech Republic, Israel
That's just off the top of my head, and of course it is my opinion. There isn't an "Official" Tier system.
Do you disagree? Or is Super league on par with Portugal, Turkey, Russia etc? If so, why is it a no brainer for a player to leave Greece to go to Benfica, Porta, Zenit CSKA, Galata, Fener, Ajax etc??
Is the concept of Greece being 3rd Tier, in the above context, really that laughable?
