Juventus are a strong team of course but I don't know how successful they can be against Sevilla in this stage. Because Sevilla have made a serious improvement in their effort in this tournament recently. That performance against Manchester United in the rematch was something else really. They were very effective at benefiting from the goal chances they had. If they manage to keep their concentration high against Juventus as well then I think they are good enough to reach the finale as well.
Juventus' performance against Sporting wasn't impressive at all. It was a really competitive matchup about the score maybe but I didn't like Juventus in any legs. I don't know if they can apply the same game plan against Sevilla as well. Considering that Sevilla are the most dominant team of the Europa League for years it will be really hard.
Juventus have won 3 Europa League titles so far, but they did it in 77, 90, 93. Juventus qualified for the Europa League final last time was in 1995 when Juventus lost to Parma. While Sevilla have won 6 Europa League titles in the modern football era where they have never failed when they qualified for the final.
Comparison of quality and mentality between the two teams is very important to guess who can qualify for the final, but I tend to think Sevilla is a team that has a good chance of qualifying if they can repeat the same scenario as beating Manchester United. Sevilla has improved, especially in terms of form. So it's only natural that their probability of qualifying for the finals is also good.
