Olympiacos vs Bayer prediction, head-to-head and probable lineups - 20 January 2026
One of the marquee fixtures of Matchday 7 in the 2025/26 Champions League group stage is set for Tuesday at the "Georgios Karaiskakis" Stadium in Piraeus, where Greek powerhouse Olympiacos hosts German side Bayer Leverkusen. Here’s a betting preview for this high-stakes clash, with both teams driven by tournament ambitions.
Match preview
Olympiacos kicked off 2026 in style, but approaches the Bayer showdown still reeling from a painful Greek Cup exit. Nevertheless, the team has found its rhythm in the domestic league and remains in contention for a top-24 spot in the Champions League stage. Their attacking play has been steady, and the return of key players from the Africa Cup of Nations could inject a burst of freshness and confidence. Still, their Champions League scoring record is a concern: just six goals in six matches.
On the personnel front, things look relatively positive. The coaching staff can count on almost all first-team regulars, except for Pirola and Biel. The returns of El Kaabi and Onyemaechi could prove crucial, especially in the latter stages of the match. With the home crowd behind them, Olympiacos will be highly motivated—dropping points here could all but end their European campaign.
Bayer enjoyed a powerful autumn, but have faltered since the winter break, both in results and in their overall play. Back-to-back Bundesliga defeats to Stuttgart (1-4) and Hoffenheim (0-1) have exposed issues with discipline and physical condition. The injury list is growing: first-choice keeper Flekken is out, Tapsoba and Tella are sidelined, and Palacios has been absent for some time. To make matters worse, key holding midfielder Andrich is suspended, disrupting the balance in midfield.
Even so, Bayer have looked strong away from home in the Champions League—victories over Manchester City and Benfica have boosted their confidence ahead of the trip to Piraeus. The team knows how to play pragmatic, effective football on the road, but this time the German club will have to cope with intense pressure from both the hosts and their own internal struggles. Bayer's current form is questionable, yet their motivation and player quality remain top-notch.
Probable lineups
- Olympiacos: Tzolakis, Ortega, Biancone, Retsos, Rodinei, Garcia, Mouzakitis, Castelo, Chiquinho, Martins, Taremi
- Bayer: Blaswich, Quansah, Badé, Beloosyan, Maza, Garcia, Arthur, Grimaldo, Tillman, Poku, Kofane
Match facts and head-to-head
- Bayer have picked up 7 out of 9 Champions League points away from home.
- Olympiacos have failed to win 9 of their last 10 Champions League matches.
- Bayer have lost their last two matches by a combined score of 1-5.
Prediction
With both sides still in the hunt for Champions League progression, the stakes could not be higher. Olympiacos are traditionally resilient at home and rarely drop points in crucial encounters. Bayer boast the best away form in the Champions League, but arrive far from their peak and hampered by personnel issues. In these circumstances, a draw—quite possibly with goals at both ends—looks the most logical outcome.
