But interestingly, last season there were also many candidates for strong teams or favorite teams in the European League who failed to go further. For example Arsenal, Man United and Barcelona. All of them failed to go any further. And it was Sevilla who managed to win the European League title last season. So I think something similar could happen. Indeed, currently Liverpool and Leverkusen are the favorites. but I think another surprise could happen this season. And it could be that the favored team stops before the final.
Sevilla are a really special team in the Europa League though. Even if they have a terrible season in the La Liga it is still not an obstacle for them to win an EL title.
Just look at their dominance in the EL in the last 10 years:

It is incredible work right?

However we don't have them in the EL this time. They just finished their Champions League group at the last position. But if they somehow managed to make it to the EL then I would definitely add them among the biggest contenders no matter what.
By the way Emery has also been very successful in these years. 3 titles with Sevilla and 1 title with Villarreal also.

He is also a great manager with a solid career.
