Agree. On the other hand, the depth of the squad is the same factor in the strength of the team as any other, which is why the top clubs at a distance look much stronger than the smaller ones whose squad is much less variable. But then I remembered a good example of a random factor: in the 2010 Inter - Barcelona match, the team from Spain was forced to travel by bus instead of flying due to a volcanic eruption, and this was later called the reason for the weak game and defeat 1-3.
