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
Although at the beginning like this in the qualifying round like this there were surprises that happened, about non-seeded teams managing to draw or even beat the seeded teams but still, in the end or in the final match later the top team or seeded team will succeed in playing in the finalmatch. But indeed, like last season at least the seeded team played against the non-seeded team in the final match but if that happens, then ofcourse the seeded team will succeed and can be sure to win, and the final match will not be too interesting.
Because after all, if the final match brings together top team v top team or seeded team v seeded team, then any result is still possible, because the teams have equally good quality or have above average quality. So, even though at this moment there is a non-seeded team that managed to make good results, they still cannot guarantee to be able to maintain their position, because over time of course there will be a revival that is successfully carried out by the seeded teams.
