This is really a poor imitation of the Super League. Of all 18 games, only 3 (I highlighted them) can be called top games and in addition, you can find 3-4 games that are of interest. The rest will be interesting only to fans of the playing clubs. In total, out of 18 games, only 6-7 are watchable - and this is with the optimistic assumption that the new format will not kill the irreconcilability of the confrontations, since this is the group stage and the value of the games is very low. The only improvement is three matchdays instead of two, but that could also be a problem as the Europa League and Conference League will have no spectators at all.
The only good thing I've seen about this new UCL format so far is the fact that you can even get to see an early UCL final clash at this league phase. Liverpool will be playing some of the best teams in the champions league this season and majority of this would be in the league phase if at all they don't go on to qualify for the knockout rounds. Even that itself is a negative because smaller teams are stacked up against each other while the big teams face off to eliminate each other. It might be the case that we would have majority of the biggest teams out of the tournament before knockout stages.
