Further up the pitch, Rafael Benitez has no new selection concerns as long-term absentees Oriol Romeu (knee) and Marko Marin (thigh) and the ineligable Demba Ba will all sit out.
Basel boss Murat Yakin is also expected to name a similar line-up to the one which played at St Jakob-Park, with few players missing from their squad.
Kay Voser is the only player currently ruled out due to injury, while the front six could be exactly the same as in the first leg.
The only anticipated change will be at the centre of the defence, where Gaston Sauro could replace the suspended Aleksandar Dragovic.
