Rennes vs Olympiacos Piraeus Prediction & Betting Tips (4 November)

Rennes welcome Olympiacos Piraeus to Roazhon Park on Wednesday 4 November 2026 for matchday four of the UEFA Europa League league phase, with kick-off now at 16:30 CET. The fixture was originally scheduled for Thursday 5 November but was rescheduled at the request of the French authorities, who could not guarantee safety and security conditions due to planned strikes and protests in France that day. Rennes sit 13th in the league phase standings with five points from three games, while Olympiacos arrive in Brittany looking to strengthen their own push toward the knockout rounds in what promises to be a tight contest under the Roazhon Park lights.

The home side are in excellent shape this season and currently sit second in Ligue 1, and they remain unbeaten in Europe after a resilient 2-2 draw away to Juventus last time out, a result that keeps Rennes very much in the mix for a seeded play-off spot. Domestically, confidence is sky high following a commanding 3-0 victory over Strasbourg at the weekend. Head coach Habib Beye can call on a strong 2026/27 squad featuring Brice Samba in goal, a back line led by Charlie Cresswell, Anthony Rouault and summer signing Gonçalo Oliveira, captain Valentin Rongier anchoring midfield alongside Ludovic Blas and Sebastian Szymański, and a dangerous front three of Musa Al-Taamari, Esteban Lepaul and on-loan striker Boulaye Dia, whose penalty threat could prove decisive.

Olympiacos, meanwhile, bounced back from a difficult away trip to Marseille in mid-October by grinding out a hard-fought 1-0 home win over Sparta Prague in their most recent European outing, a match in which the Greeks dominated possession and created far more chances than the scoreline suggests. Mendilibar's 2026/27 squad blends experience with quality: Manolis Saliakas, David Carmo, Lorenzo Pirola and Marcus Holmgren Pedersen form a solid defensive unit, Kostas Fortounis and Gustavo Sá pull the strings in midfield, and the prolific Ayoub El Kaabi is supported up front by Roman Yaremchuk, giving the visitors more than enough firepower to trouble any defence on the continent.

In the European 1X2 market, Rennes are priced as moderate favourites at around 2.10 for the home win, with the draw available near 3.50 and an Olympiacos victory quoted at roughly 3.40. Those odds reflect Rennes' strong domestic form, their unbeaten European run and the advantage of playing in front of their own fans, while also respecting Olympiacos' pedigree and defensive organisation. With both sides needing points to climb into the seeded positions, we expect an open, entertaining game with chances at both ends — but Rennes' attacking depth and home momentum should just about tip the balance. Our prediction: Rennes 2-1 Olympiacos Pira
