If you know enough about the Greek League to state with such authority that it's better than another League, then yeah, you should be able to name the teams that play in it, otherwise it's clear you know nothing about it. How can you truly know the quality of a League if you don't even know who plays in it?
And when it comes to Europe, a Greek side has never won a club trophy, whilst Scottish teams have, and in recent years there hasn't been much difference between the Scottish and Greek sides in Europe. Hardly proof that the Greek League is miles ahead of the Scottish one
Anyway, Ijjy has himself admitted that he wasn't being sincere with his original comment, so we can move on
