Still don't understand how this is any different from the old format. There were blow out matches every round back then as well. Now at least we don't have dumb groups that ensure a mediocre team advances, or that a top team will have to play EL
You had groups of 4 where everyone plays everyone. Twice.
99% of the time, the 2 best teams had a fair chance to go through, based purely on their own performances.
The schedule plays a stupidly important role in any league where everyone doesn't play everyone, there's a much better chance that an inferior team gets a favorable schedule and takes advantage of it.
Just look at this season.
PSG has 4 pts so far. PSG's schedule: Girona, Atleti, Arsenal, City, Stuttgart, Bayern, PSV, Salzburg.
2 La Liga, 2 EPL, 2 BuLi - 2 from non-top-4 leagues.
Dinamo Zagreb has Celtic, Salzburg and Slovan Bratislava.
There's a fair chance that Dinamo gets more points than PSG just by winning those 3 winnable games (they've won 2 and are still to play Celtic).
At the same time, I watch the Dinamo games cause it's a Croatian team.
(though tbf I only watched bits yesterday vs BVB as Dinamo had their entire midfield out, starting GK, half the defence and the #1 striker... it was never gonna happen, was just a case of how many they concede... had to play a 17 year old with zero appearences at senior level in midfield).
But I also don't watch Sturm-Crvena Zvezda. And games like that. Nor do I expect neutrals to watch Dinamo - Slovan.
Dinamo is a Croatian team and I'll take it if they go into the next phase, but in no serious world are they in any way comparable to PSG - and there's a realistic chance that happens, based purely on luck and schedule.
They fairness and integrity of the competition suffers because UEFA wanted more money.
So, IMO, there's a MUCH bigger chance of mid teams advancing and serious teams suffering to schedule, than in the prior format.
