Puzzling.
The Champion's League does a good job as it provides the best matches in the World at the highest level (as opposed to the best matches in the World at the lowest level?)
Most of the best teams are in Europe anyway, so any competition that pits them against each other will provide the "best matches". That is why they have the current format, because whichever one they choose they are on a winner, so they choose the format that makes the most cash.
I'm not jealous of it, how could I be? I don't organise my own league competition! If you mean instead that I am envious of other teams competing at European level whilst we do not, you're miles out. I've had years of Rovers being in the Second Division, I can accept other teams being more successful, and what is more, I enjoy watching teams like Barca play.
What sticks in my craw is the top teams sticking their noses in the trough for ever-bigger bundles of dosh whilst smaller teams go to the wall. And that goes for the Premiership as much as the Champs League, so maybe I'm jealous of teh Premiership too. Ooops.
