Reporter's view (Carlos Machado, UEFA.com): Whose morale will be restored first? Both sides are reeling from big domestic defeats – Porto lost 2-1 at home to Benfica on Saturday, while Lazio beat Roma 3-0. If they score and don't concede, Porto are through, so Éder Militão's return is a real fillip – he should join Pepe, Felipe and Alex Telles in a tough defence. Francisco Soares, meanwhile, may be the man to partner Moussa Marega up front. Could these changes make the difference?

Marega v Manolas: Porto lacked penetration in the first leg without their five-goal leading scorer, but fit-again Moussa Marega will lead the charge on home soil, where he has struck in every UEFA Champions League outing this season. In his way, illness permitting, will be Kostas Manolas, Roma's most reliable defender, whose success or otherwise in limiting Marega's influence will go a long way to deciding the outcome of this finely poised tie.

Sérgio Conceição, Porto coach

We have to win the game, but there is no rush. We have to be consistent defensively. Roma have the third-best attack in Serie A, so balance will be key. Our self-belief comes from the work we do every day, not from any individual player.

Having extra options is important, but it's not always decisive. What matters is the team. If we do ourselves justice, we have a great chance of reaching the quarter-finals.

Eusebio Di Francesco, Roma coach

We will have to be determined and defend the advantage we have – and look to hit them on the break when we can. We'll need to be very switched on defensively throughout.

Every player in the squad knows they need to be ready to play at any moment and no one knows the team we will pick. I want to decide, in the end, by looking into the players' eyes and seeing who is most ready for the battle.
