Sevilla recent form is amazing and their performance against Manchester United in both matches were at the top of game which bring them into last four with most chances they can win from here because Juventus is having serious decline in their performance and their fight for the top four in Serie A is also having problem so with this we can expect tough situation for them even it's never been easy for any team but here most chances Sevilla is having good advantage specially after staying into relegation zone now they are at 11th with lost against Girona at home give them shock but right now they are capable of having recovery from this lost and fight hard for the final spot.
In recent time we have problems in Juventus which are clearly showing things are not favorable for them but still Sevilla and Juventus could be the toughest match with anybody can go through in this season we have good results from Italian sides which is also good for them.
Juventus could make a comeback against Sevilla too, we need to keep that in mind. Juventus is not a bad team, they are a good team going through a rough period right now, and that happens, so they could keep being bad and lose to Sevilla as well, which is possible, or they could stop being bad and start winning again and beat Sevilla as well, which is possible.
We are not sure which is going to be the case, I still think Juventus has the better roster and they will end up winning, they are doing as well as hoped for and when considered where they are going to end the season, third in serie A seems like a better deal than wherever Sevilla ends up in la liga, so we can consider Juventus as the better team, shouldn't really be considered too bad.
