Having looked at the new Champions League format coming season after next, I'm sorry to say that I kind of love it.
No guarantee it will work this way in reality but the idea of playing ten teams from vastly different leagues sounds better to me than the current structure. There are far too many meaningless matches in GW5 and 6 of the group stages every year, this solves that. And if, say, PSG draw a much weaker team from somewhere like Israel, they're not basically guaranteed six points under the new structure.
Only downside is the wildcard spots.
