In fact, Sevilla's performance was good but not well enough to beat a strong team like Manchester United, they focused on this match because the Europa League in their only hope but I think the reason why they won the game was the bad performance of Manchester United against them that's why if Juventus don't do the same mistake they won't have a hard day against Sevilla.
I think Juventus are well aware of that at this point because they are already in the semifinals of the Europa League this season so it will be very detrimental if Juventus are not focused and consistent to win and go to the final. Because if for example Juventus can make it to the Europa League final this season, Juventus will also not face such a strong team in the final because AS Roma and Leverkusen are also teams whose performances have been mediocre this season.
Juventus are in a decline at the moment and the Europa League trophy is the only remaining trophy that is still possible for them to win of course they will be very focused on the Europa League semi-final match against Sevilla.
Juventus and Sevilla are both teams that are currently slumping in their respective domestic leagues, but their performance on the Europa League stage is very different, maybe because of greater motivation so that the best performance of these two teams is always shown so that now they have made it to the semifinals.
I think these two teams have the same chance to get to the final, neither one is the favorite because the quality of the two is not much different so that the chances of both to win are still the same.
