Mansion Sports – The UEFA Champions League returns with another thrilling encounter as FC Barcelona prepares to host Olympiacos F.C.. 

The match is scheduled to take place at Estadi Olímpic Lluís Companys on Monday, October 20, 2025, at 21:00 local time.

This fixture presents a golden opportunity for Barcelona to secure their second victory in the 2025/2026 league phase, while Olympiakos will be fighting to earn their first three points of the campaign. 

With Barcelona aiming to rebound from an inconsistent run and Olympiakos determined to register their first goal in European competition this season, the clash is expected to be intense.

The passionate support from the home fans promises to create a heated atmosphere at Montjuïc. 

Before kick-off, here is a closer look at both teams’ conditions and a predicted lineup for Barcelona vs Olympiakos 2025.

Team Conditions Ahead of the Match

Barcelona

Barcelona currently sits in 16th place in the Champions League league phase standings. After a narrow win over Newcastle United F.C., they suffered a 2–1 defeat against Paris Saint-Germain F.C.. 

Their struggles continued with a 4–1 loss to Sevilla FC in La Liga, making the international break a rather tense period for Hansi Flick’s squad.

Momentum returned during the derby against Girona FC, when a last-minute goal by Ronald Araújo secured a dramatic victory and boosted team morale ahead of El Clásico.

Barcelona has a strong historical record against Greek clubs in European home matches, including a 3–1 win over Olympiakos in October 2017. Moreover, head coach Hansi Flick also has fond memories of facing Olympiakos from his time at FC Bayern Munich, defeating them 2–0 in 2019.

Despite the upcoming El Clásico, Barcelona is expected to stay focused and field a competitive squad to maintain their home dominance.

Olympiakos

Olympiakos returns to the main stage of the UEFA Champions League for the first time since the 2020/2021 season after winning the Super League Greece last year. 

Under the guidance of José Luis Mendilibar, they opened their campaign with a goalless draw against Pafos, despite having a numerical advantage for most of the game.

Their loss to Arsenal F.C. dropped them to 29th place in the league standings. However, a 2–0 win over AEL Larissa F.C. in the domestic league, courtesy of two goals from Ayoub El Kaabi, has revived team spirit.

The challenge remains steep: Olympiakos has not won any of their last 11 group-stage matches in the Champions League. Additionally, Mendilibar has recorded 23 defeats in 27 encounters against Barcelona, adding further pressure on the visitors.

Predicted Lineups for Barcelona vs Olympiakos 2025

Barcelona (4-3-3)

Barcelona continues to grapple with several injury concerns. Joan Garcia, Marc-André ter Stegen, Gavi, and Dani Olmo have all been ruled out. Robert Lewandowski will also miss around a month with a hamstring injury sustained during the international break. 

Raphinha is still regaining full fitness, and Ferran Torres is working to be match-ready. Flick is likely to rotate key players to maintain freshness ahead of El Clásico.

Olympiakos (4-2-3-1)

Olympiakos will be without Rodinei and Gabriel Strefezza due to injury, while Nikos Botis and Rémy Cabella were not included in the Champions League squad. El Kaabi will serve as the key figure in their attacking strategy to breach Barcelona’s defense.

A Clash Beyond a Group Stage Fixture

This match represents far more than a standard group stage game. For Barcelona, it is an opportunity to reinforce their dominance at home and climb the standings ahead of their high-profile rivalry match.

For Olympiakos, it is a chance to defy the odds and end their disappointing streak in European competition.

Who will emerge victorious in the Barcelona vs Olympiakos 2025 showdown? The answer will be revealed the moment the referee blows the opening whistle at Montjuïc. 

One thing is certain: the intensity and atmosphere of this match will be nothing short of electrifying.
