Olympiakos and Bayer Leverkusen faced twice in the UEFA Champions League 2002-03 first group stage – the Greek side won 6-2 at home before a 2-0 win for Leverkusen at the BayArena.

Bayer Leverkusen are winless in their last three away major European trips to Greece (D1 L2) since beating Panathinaikos 4-1 in the Cup Winners’ Cup in October 1993.

Olympiakos’ most goals in a UEFA Champions League game and biggest win margin was in a 6-2 win over Bayer Leverkusen in September 2002. Since then, the Greek side have averaged 1.1 goals per game (110 goals in 101 games), netting more than three in just one game (4-2 vs Malmö FF in December 2014).

After 10 winless UEFA Champions League games (D2 L8), Olympiakos won 1-0 on MD6 against Kairat. The last time the Greek side ended a 10+ game winless run in the competition (13 games between November 2015 and November 2019), they won back-to-back matches, beating Crvena Zvezda and Marseille 1-0.

Bayer Leverkusen are unbeaten in their last 19 major European matches against sides from outside Europe’s big-five leagues (W14 D5) since a 3-0 defeat to Portugal’s FC Porto in October 2022.

Olympiakos have had 89 shots in six UEFA Champions League matches this season, an average of 14.8 per game which is their highest Opta has on record since 2003-04. They’re averaging 4.7 shots on target per game (28 in 6 games), their best since 2014-15 (33 in 6 games, 5.5 per game).

Across MD4, MD5 and MD6 in this season’s UEFA Champions League, only three sides conceded fewer goals than Bayer Leverkusen (2). However, their opponents underperformed their xG by 3.5 goals in these matches (5.5 xG), with only Galatasaray’s opponents underperforming more (-4.2). By contrast, in this timeframe Olympiakos’ opponents have overperformed their xG the most (2.2 xG, 5 goals, +2.8).

Only two players – Vitinha (97) and Joey Veerman (95) – have made more line-breaking passes than Bayer Leverkusen’s Aleix García (85) in the UEFA Champions League this season. If the Spaniard plays in this match, he’ll come up against former manager José Luis Mendilibar, who he played under during his time with Eibar.

Based on the xG of shots on target faced (excluding own goals), Olympiakos’ Konstantinos Tzolakis is the worst-performing shot stopper in the UEFA Champions League this season, conceding four goals more than expected (13 conceded from 9 xG on target).

Malik Tillman has averaged 71.4 high-intensity pressures per 90 in the UEFA Champions League this season; the most of any player (min. 300 minutes played). Meanwhile, teammate Christian Kofane has averaged the most per 90 of any striker in this season’s tournament (68.6).
