So yes, playing against Juventus will in fact still give Sevilla a chance to win, but that doesn't mean I consider Juventus weak because in fact Juventus' performance seems to be steadily declining. Thus, Juventus and Sevilla have a different trend where Juventus is becoming unstable, but Sevilla seems to be more consistent and stable in this moment.
The conditions are still possible for both teams because regardless of anything the opportunity is still there.
The first leg Juventus will play at home is clearly favorable for them but with this in mind I feel that Sevilla will still follow the same strategy by trying to draw the game and make a splash for the second leg at the Ramon Sanchez-Pizjuan.
I think Juventus is in a great form but so is Sevilla lately except the last game at home where they lost 0-2 against a team at the same level as them in La Liga.Juventus won tonight against Lecce in Italy and it is in second place so far in Serie A and individually Juventus I think it has better players.I think so because I don't think Sevilla has players of the caliber of Di Maria or Vlahovic beside some other strong names and therefore I strongly agree with you that Juventus is a heavy favorite in the first leg that will be played in Turin.
Of course Sevilla at home has shown that plays great games in Europa League and their destroying of Manchester United is a great proof of such thing so anything can happen in this 2 tier encounter.
