Sevilla's level is still far from UCL. Even though this club was able playing in UCL but the result will always be the same. Being able to compete in UCL is already a huge achievement for sevilla. I don't even put a lot of hope for this club.
Sevilla needs more than a miracle to go to the play off stage with the current squad. Although I don't want to be pessimistic about Sevilla's performance, it's necessary to consider the possibility that they might be in a less-than-ideal situation presently and we should take that into account.
I would like to value qualifed for UCL play off is a higher achievement compared with winning europa league. It's caused by sevilla is in financial crisis and the club in the needs of money to solve that.
I mean as long as they end up going back to europa and not be the fourth, that would be fine for them. They always look weak and then somehow they make it work. Last season they beat United, Juventus and Roma all with incredible play, nobody gave them any chance and they either got super lucky or they just did it with some hard work but they managed to get it.
I could say United was pure luck, and I could say Roma was referee issue, but at the end of the day they got it. If they can pull it through and be third at least, they could go back to europa and that would be good for them. They can go further there with some lucky drawing, which would be a good case for them on the long run which can make it happen.
