Olympiakos and Real Madrid will meet for the ninth time in European competition, with all eight to date coming in the UEFA Champions League. The Greek side have only beaten them once to date (D3 L4), doing so in December 2005 on home soil (2-1).

All four of Olympiakos’ defeats against Real Madrid in the UEFA Champions League have come away from home. When hosting the Spanish side, they have gone unbeaten in four matches against them (W1 D3), while scoring more (5) than they have conceded (4).

Real Madrid are looking for their first away win to Olympiakos, on what will be their fifth attempt. The only team they have faced more than four times away from home in their European Cup/UEFA Champions League history without winning is Milan (7 – D2 L5).

Real Madrid have lost three of their last four away matches (W1) in the UEFA Champions League, while failing to score in all three defeats (0-1 v Atlético Madrid, 0-3 v Arsenal and 0-1 v Liverpool). This is the first time they’ve had as many as three losses within a four-game spell away from home in the competition since November 2007-October 2008 (W1 L3).

Of teams with at least 20 wins in European Cup/UEFA Champions League history, Olympiakos are the side who have the highest percentage of their victories coming in home matches (85%), with 40 of their 47 wins coming on home soil.

Only 15% of Real Madrid’s chances created in the UEFA Champions League this season have come from the right-sided attacking third; the second-lowest percentage by any team in the first four matchdays, only behind Bayer Leverkusen (14%). Indeed, they led all sides for chances created from both the left-sided third (27) and central third (30) in the same period.

Olympiakos have averaged 120.5 high-intensity pressures in the final third per game in the UEFA Champions League this season; the most of any team through the first four matchdays. Indeed, striker Ayoub El Kaabi was the only player with 100+ high-intensity pressures in the final third in this period (115).

Real Madrid forward Kylian Mbappé has been directly involved in 43 goals in 43 away games in his UEFA Champions League career (32 goals, 11 assists). Of players with 10+ away matches played, the Frenchman has the best goal involvements per away game ratio in the competition’s history (1).

Olympiakos’ Chiquinho made the most successful crosses from open play of any player in the opening four matchdays of this season’s UEFA Champions League (7), as well as creating the most chances from open play crosses (5).

Real Madrid pair Kylian Mbappé (6) and Vinícius Júnior (4) have created 10 chances between themselves in the UEFA Champions League this season; the most between any duo across the opening four matchdays of the current campaign.
