I think it would be the best thing to happen for the competition, a less unpredictable competition for once, fresh faces in final stages.
Not sure why everyone thinks we all glory supporters.
What the football establishments need to do is be strong and impose a punishment that tells them dont try this crap again, if they just all let back in the competitions as if nothing is happened, all that will achieve is trying more crap again later, knowing they can get away with it.
I think a 10 year european ban for the ringleaders, 4 year ban for other participants, and rolling 30 point deduction for next 4 seasons in domestic leagues would be adequate.
On top of this a ban from the 6 clubs of having a member of their board on the uefa board for 2 decades.
