Ur basing this off of hypothesis of what will happen. Big clubs can right their ship easier than smaller clubs. Man U is not beating chelsea 6 games all the time.
I rather see the best teams grouped together than the current system.
But they're not the best teams! Tottenham and Man City have never won the Champions League. Arsenal haven't qualified for the CL in 5 years. Bayern won the CL last year and they're not in it. Atalanta, one of the most entertaining teams of the last few years, beat Juventus yesterday and made it farther in the Champions League last year than Juventus has in almost a decade. Juve is in the Super League, Atalanta will never be.
This isn't a competition of the best teams, it's a competition of the teams with the biggest checkbooks. It means the sport is no longer a meritocracy. It'd be like Duke making the tournament every year regardless of record.
