it is not certain given that the results this year can change as we have already seen, and it is no coincidence if teams like these manage to score and move forward in the competition, it is not easy but not impossible so everything is up to them to commit and show that even small things can hurt
A mediocre club like them often makes the big teams unprepared and brings surprises and different colors, as achieved by Lille when they beat Real Madrid they played quite well in any aspect not being careless in closing the space is a good thing they showed. So I think the same as you said that these small teams usually make the standings more chaotic but in the end they will also come out maybe in this round they can be a little bit of a tunnel but walking again I think the small teams are gone
