The Ligue 1 giants head into matchday five in the knowledge that a win could seal their place in the last 16. Similarly, Valverde's men could be eliminated at Stade Velodrome

Olympique de Marseille boss Didier Deschamps is set to recall Mathieu Valbuena to the starting line-up after the diminutive winger sat out Saturday evening's 1-0 defeat to Montpellier. Lucho Gonzalez, who scored the winner when the sides met on matchday one in September, is also likely to return to the fold after coming off the bench at Stade de la Mosson.
Stephane Mbia has been out since August with a broken metatarsal, but the Cameroonian defender could be in contention after making the substitutes bench at the weekend. Rod Fanni is also out after breaking a toe against Arsenal last month, with Nicolas N'Koulou deputising in defence.
Ernesto Valverde has various injury concerns to contend with ahead of his side's do-or-die trip to France. Ariel Ibagaza, Jean Makoun (both knee) and Pablo Orbaiz (groin) have not made the journey, with Lubomir Fejsa overcoming a strained foot to take his place. Kevin Mirallas makes his second trip west after featuring for Belgium against France last week.
Tassos Papazoglou underwent surgery for a knee injury, with David Fuster and Djamel Abdoun travelling after recovering from recent knocks as the Greek champions look to prolong their stay in the Champions League.
