At this point Sevilla is a sure target towards LaLiga 2 because it's clear that current team have no desire to actually play football and save this club for a real disaster that is relegation. It will also be the first time in club history when they will face this situation and the fact that they are in debt over 800 mil $ makes me thing they do want to go to LaLiga 2 and re-build a fresh team there under a new project.

It doesn't look like Sevilla has any hope of surviving in La Liga and they are now increasingly miserable because they sit in a position close to relegation. Several years ago they were a strong team in La Liga but for some reason they fell so deeply recently that they were unable to compete with even weak teams. Sevilla seemed to be running out of time and the previous defeat against Athletic Bilbao also hit them hard.
I would say that even if Sevilla's performance is weak now, this team will qualify for La Liga eventually. Sevilla are still out of the relegation zone. However, Sevilla team is only 1 point ahead of Cadiz who is in the relegation zone. However I would say there is still a long journey ahead. Sevilla will play 19 matches in La Liga. If Sevilla can sort out their problems in these 19 matches, and stabilize the team a bit, they will be able to move up the points table.
Sevilla have won just 3 of 19 matches this season. The main reason for Sevilla's defeat was their poor defence. I think Sevilla's performances will be strong and regular if the defense is a bit stronger.
