Olympiacos will aim to stretch their European winning run to a fourth straight victory this season when they face Stade Rennais at Roazhon Park. 

Olympiacos come into this match on the back of a thrilling 3-2 win over Kifisia in the Super League Greece. They started the game on the front foot and consolidated in the second half when strikes from Joel Roca and Marius Mouandilmadji doubled Olympiacos' lead. However, the hosts staged a fightback as Jordi Mboula and Gerson Sousa levelled the score. It took Gelson Martins' added-time goal for the Red and Whites to grab maximum points from the match to keep the pressure at the top of the table. 

Since losing to OFI Crete in mid-September, Olympiacos have gone on a nine-game victory streak across all competitions, and this included three narrow triumphs in the UEFA Europa League over Jagiellonia Bialystok, Marseille and Sparta Praha. With nine points from the three matches played in Europe this season, head coach Imanol Alguacil's men sit fifth in the Europa League standings. They are also unbeaten in their last 10 Europa League group/league phase matches. 

Meanwhile, Stade Rennais will hope to protect their own unbeaten run in the Europa League, as they recorded one win and two draws till now. Franck Haise's men are yet to lose in their backyard this season across all competitions, and we can expect that only a monumental effort from Olympiacos could get them past the French side. 

Despite their positive home form, Les Rouges et Noir have faced defensive problems, which included a 5-2 defeat to OGC Nice in their last match in Ligue 1. Rennais have already faced Greek opposition in the Europa League this season. They prevailed in a 2-1 victory over OFI in Matchday 2. However, their third European game ended in a 2-2 draw with Juventus. 

French top-flight top scorer Esteban Lepaul continues his recovery from an ankle sprain, which is set to keep him out of the clash. 

Musa Al-Taamari is expected to start the match after scoring against Juventus. However, Boulaye Dia is set to hit the bench, 

As for Olympiacos, Alguacil will be without the services of Kostas Fortounis, Yusuf Yazici and Ayoub El Kaabi due to injuries. 

Armando 'Hormiga' Gonzalez is predicted to start the game after resting in the previous league outing. 

Stefan Ortega is set to start in between the sticks as Balsa Popovic has been appointed to feature in the Greek Cup and less critical fixtures.
