Doesn't matter.
You think Osasuna or Valencia is better than Sevilla or will finish ahead of SEvilla in the end?
Nope!
They had a rough patch of results, prob won't qualify for CL this season, but that doesn't change the fact that they are among the top-7 top-8 LL sides
The problems they gave us in the game were far more nuanced and hard to cope with than whatever Osasuna or Valencia can give us
It does though.
Osasuna is currently the better team/in better form than Sevilla.
Sevilla playing like a team that won't finish top 10 tbh, WOAT summer transfer by Monchi tbh, Lopetegui time was clearly over and they retained him (probably due to financial reasons), oldest squad in Liga, mediocre signings while their best players left.
The chances of Osasuna ending in better position is actually very real, unless something in the equation changes(new coach or new winter signings)
