To be honest, if sevilla was not a party who has been wiping united from europa league. Its own players who have wiped Manchester united. There are so many blunders from the players. This is the main reason why united lost against sevilla. Meguire was making so many goals against united.
Juventus may be able to perform even better compared with manchester united. It's caused by juventus will be able to play even more consistently. Juventus never lost against Sevilla in the previous meetings. The condition might be different if MU was able using its best defensive line but the fact said other thing about it now. Sevilla is the one who has been qualifying for the semifinal against juventus. Juventus was not doing so well in serie a but im sure allegri will be thinking so hard about how to win against sevilla.
Juventus had been facing crisis in the attacking lines. Allegri had to deal with some injured players. Allegri must think which best formation to be used against sevilla. This is also an advantage for sevilla at this moment.
