Juventus must have watched the match between Sporting Lisbon and Arsenal, which resulted in Arsenal's elimination from the Europa League. They did not waste their counter-attacks against Arsenal and scored as soon as they had the opportunity.
Seeing from how sporting performance against Arsenal, Juventus must be careful enough in facing this club. Although Sporting is not as popular as other clubs in UEFA Europe League, in fact, they are strong enough so far. So, I think that Juventus must be more serious about facing Sporting. Moreover, Sporting has strong defense and they are also able to optimize even a small chance to make a goal.So, this will be still a very attractive match to wait.
The Juventus team is now taking every match very seriously. Because Juventus don't want to make any more mistakes. Currently there is no such thing as a weak team, every team is capable of building their own. That's why Juventus will never take Sporting team lightly.
Juve is a very complete team, of course they should be aware of how Sporting Lisbon is playing, but to be honest I have seen Juve much more Focused, not only because of the quality of their players, they also want to show They are the best, for me a good final Would be between Juve and Man United, both teams are good soon, they have also failed greatly in many games, for me they are on an equal footing and that is something they should take into consideration When it comes to Facing each other, they have great needs and that is what makes them unique.
Leverkusen have been doing an incredible work for so many weeks. Xabi Alonso effect is really true now.

It must be good for his manager career as well because this is like his most serious manager experience with a big team. So far he has done a great work in the Bundesliga first of all. The team are near a spot for qualifying for a tournament in the standings now. They are really impressive in the Europa League on one hand too.
While they are in a great shape I think they have what it takes to eliminate Royale Union SG in this stage as well. The Europa League title is their only realistic way to make it to the Champions League now. They should be doing their best here.
Leverkusen have consistent performance after arriving Xabi Alonso and he was success give one place in Europe League after get finished on third position standing in Champion League group stage. In Bundesliga Bayern Leverkusen standing slowly up to top standing position when first time Alonso arrived almost dropped to relegation zone.
In Europe League, Leverkusen success eliminated strong Ligue 1 team AS Monaco on playoff round and Ferencvárosi on 16th round, seems not difficult with Royale Union SG for defeating by Leverkusen and has chance for Alonso with first time career as manager lead to semifinal in Europe League.
I would really like Xabi Alonso to reach the Europa League final, it seems to me that he does things well, and Leverkusen is a team that I have always considered particularly strong, here there is a belief that the strongest is the Manchester United, I am not a believer in this, for me there is Juve before Manchester now, if Leverjkusen manages to win the Europa League it would be a great achievement for the team and especially for Xabi Alonso, it would be something great and again, although I am a fan of Juve.
