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.
I agree with you. It cannot be said that Juventus' performance against Sporting was very good. Sporting played well enough. Sporting's performance was even better than Juventus's in the second leg. Juventus were able to qualify for the semi-finals due to being an experienced team. There is no way to call the Sevilla team weak. The Sevilla team had a great performance against Manchester United. And if they can put up a similar performance against Juventus then I think Sevilla will be able to qualify for the final.
