I am also touching Benfica's match on the grounds that it is not possible to exclude all three Portuguese players. It will be a huge surprise. Benfica want just like Porto half a goal to go after losing 2-1 in the first. I don't know if I should consider Shakhtar a Champions League team since it comes from. But he is clearly a viable opponent. I hope the fatigue from Benfica's constant struggles does not seem to matter and at least one Portuguese from both passes (at worst).
