Nuno Espirito Santo's side make the trip to Belfast with one foot in the next round, although the Portuguese has a number of decisions to make regarding his starting lineup for Thursday's game.
Here, Sports Mole takes a look at what players could feature at Seaview as both teams aim to earn a fixture against either FK Jablonec or FC Pyunik.
Despite being cleared of any serious injury, Ruben Neves's spot in the starting lineup remains in doubt as a result of a side injury sustained last week.
Matt Doherty is still out of contention as he continues his recovery from a knee problem, while new additions Jesus Vallejo and Patrick Cutrone are ineligible for this game having signed for Wolves midway through the tie.
Raul Jimenez is another potential inclusion having made an appearance in the second half during the first leg, just days after returning for pre-season training due to helping Mexico win the Gold Cup.
The forward may be given an hour, which could result in Morgan Gibbs-White dropping down to the substitutes' bench, but midfielder Romain Saiss may be given more time to ease his way back into action after playing for Morocco at the Africa Cup of Nations.
