Theoretically, since we don't have Manchester United in this tournament anymore because of the mistake they done Juventus can be the first hope for the Europa League this season, and they will have to win the game against Sevilla while they are the most unpredictable team in Europa league and if Juventus don't make the same mistakes like Manchester United there is a high chance for them to beat Sevilla.
Sevilla also has the same chance of winning the match, so it shouldn't be just Juventus who have a better chance. Seville's form has improved so far, the team is getting more and more confident in every game and they don't look to be underestimated in this competition. I wouldn't even be surprised if Sevilla beat Juventus, that's normal for me.
The chance for both teams to qualify for the finals are 50:50, and whichever of them succeeds should be the favorite for the title. I like Sevilla to do it, but Juventus deserve it anyway.
