I can't even put the result from previous match as a reliable data to determine the outcome from the upcoming match. It's very hard to predict. Sevilla was also facing lose against girona recently which was also putting sevilla in another decline for its mentality yet europa league is different compared with domestic league as the team is only having a chance to win the trophy or it will back home. Juventus may able to perform differently when it will be facing sevilla soon.
Sevilla will be facing juventus without some key players which were able contributing a lot for sevilla. The match between a team from spanish league vs italian league will always become a very interesting thing to be watched.
Yes, the 0-2 home defeat to Girona only underscored how lucky Sevilla were to beat United. Although it would seem that the score is 3-0 and the overall score is 5-2 in favor of Sevilla, it hints that supposedly Sevilla was really stronger. But in fact, Sevilla was lucky to beat United, which were in a functional hole due to a difficult calendar. So far, I don't see what kind of luck will help Sevilla beat Juventus even if Sevilla plays in the optimal lineup.
