Juventus will indeed have a really tough work to do in the second leg. Because Sporting's performance was really impressive in Turin already and this could be a sign of another solid effort in Portugal this time. Sporting are very likely to miss their chance for a Champions League spot in their domestic league now. They seem focused on the Europa League more than the Liga Portugal.
Winning the Europa League title isn't an easy task at all but it looks like they will still try their luck with that. Honestly their performance until this round has been impressive. Therefore Juventus had better be well-prepared for facing a tough opponent once again.
Of course Juventus will have difficulties when they travel to the Jose Alvalade stadium in the second leg match against Sporting. Juventus are not safe enough because they only won narrowly in the first leg so Allegri must be able to maximize his team to perform better in the second leg.
I am pessimistic about Juventus in the second leg because lately they are in a bad condition in Serie A which could be fatal if they can't maintain their form in the second leg.
but the quality of juventus in the europa league is still very much counted on they are a big team which most likely the dealer will provide quite tempting odds for this match.
