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.
The fact that if sevilla was able beating manchester united with the help from some of its players. I meant some players owned by manchester united like meguire, de gea and malacia contributed a lot for the win of sevilla. Sevilla can't expect the same thing to happen once it will be facing juventus soon. juventus is really strong at this moment even though it has got very bad result against napoli which has been leading the standing in serie a right now. People shall also try to remember that without meguire, malacia and de gea. Sevilla was nothing for manchester united. Sevilla must be so thankful with the performance from those players caused by those players made the way of sevilla to go to the semifinal become much more easier.
Juventus had better chance to beat sevilla at this moment. Sevilla knows so well about how strong juventus is right now. Sevilla is really be careful before it will be facing juventus.
