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.
I have seen the results of the poll for the semi-finals, where the voters who have voted are 11 participants and who have chosen Sevilla as a strong candidate to advance to the final are 6 of whom I am one of them. Sevilla is big and very strong team after they were able to beat manchester united in the previous match which indicates they really want to defend their crown as a quite successful team in the europa league for this season.
Juventus will definitely try hard to beat Sevilla at home to strengthen their situation when they travel to the Sanchez Pizjuan stadium in the second leg. The first leg will take place on the 12th of May where both teams can prepare their best form for the first leg of the semifinals.
