Rennes vs Olympiakos prediction: Are Rennes the favorites? (04/11/2026)

Rennes host Olympiakos at Roazhon Park on Wednesday in the Europa League’s fourth round, with both teams unbeaten in the competition. Rennes sit 13th after drawing 2-2 with Juventus; they have been strong at home but inconsistent, conceding 11 goals in their last four matches, including a 5-2 defeat to Nice. Olympiakos are fifth, four points ahead, and arrive on a run of nine straight wins, including five consecutive away victories. The suggested bets include a Rennes win and decisive contributions from Boulaye Dia or Adrien Thomasson.
