it is bad actually.
It is worse for small clubs(i mean not too small but still, they have history but currently they are not elites either) like ajax, porto, lyon etc, whose revenue comes from big underdog stories in champions league. by ESL rich clubs become richer and poor become poorer. we wait for big games to happen, but imagine if there were big games everyday, it would become normal for us. It will increase fixture congestion too, so more injuries.
