Since Sevilla got rid of the more favored team, it's only natural that they become another favourite, even though in the domestic league they are far from what was expected. Juventus must be careful with this team, because Sevilla can surprise them at any time. Manchester United were their victims before, although that was supported by Manchester United themselves who did not perform well in that match and made many mistakes.
Juventus must have seen who their opponents were in the semifinals of the Europa League and Juventus have also never underestimated any opponent they have faced so far. And of course Juventus will be very careful with Sevilla because every team that has entered the semifinals in a competition like the Europa League must be considered good because each of them certainly has advantages. So you should be careful and there is no reason to underestimate it.
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.
