sevilla is favourite for the cup, beating the best team in the cup and getting to the far, means that they are favourite, juventus is another contender. both team can meet in the finals. they have been outstanding in the league. but i wish Sevilla wins
They already have 6 Europa League trophies and they are a big name in Europa League. In this season Sevilla don't have their best performances in La Liga and Europa League but when the season comes to its ending, they likely are getting their best back. The big win against Manchester United in quarter final sounds like their alarm to Juventus and other three clubs that Sevilla are really ready to win Europa League again.
Apart from that, Roma vs Leverkusen will be more interesting to follow because Alonso will provide an interesting achievement for Leverkusen if he is able to bring Leverkusen through to the final. Meanwhile, jose mourinho is a coach full of experience that can make this match colored with a pretty hot atmosphere.
Leverkusen did have bad months before the appearance of Xabi Alonso at their coach position which helped them to improve and have a very good impressive streak in Bundesliga. These matches between AS Roma and Leverkusen will be first times Xabi Alsonso faces with Jose Mourinho as coach fighting so it would be interesting for both of them.
Against Juventus in the semi finals, Sevilla will play the with the belief that they're good enough to challenge anyone in the competition and still win comfortably. But when we talk about quality of players and which team has a better chance to progress to the finals o think Juventus does. I'll go with Juve just a bookmakers
Juventus have better quality as they have more star players and in reality, with real performances and results, Juventus have better position in Serie A than Sevilla in La Liga. We are all aware that Sevilla just moved beyond the relegation zone in latest weeks but they still need to maintain good performances in remaining matches to be safe and not be relegated after all.
Quality of players are different but not too considerable between two clubs. I don't think it will help Juventus too much in semi finals.
