Arsenal is set to face Olympiacos at the Emirates Stadium in a Champions League match today, October 1, 2025, at 8 pm BST. Coming off a dramatic 2-1 victory against Newcastle in the Premier League, the Gunners are aiming to secure their second win in the Champions League.

Manager Mikel Arteta is likely to rotate the squad, balancing the need to keep key players fresh for the upcoming match against West Ham United and the desire to maintain a strong performance in the Champions League. Arteta has acknowledged the challenges of squad selection, having discussed rotation strategies with the players. He emphasized that players are aware of the plan and will have opportunities throughout the season.

Arsenal has some injury concerns with Gabriel Jesus, Kai Havertz, Noni Madueke, and Piero Hincapie sidelined. However, Martin Ødegaard has returned to the squad after recovering from a shoulder injury.

Potential changes to the lineup could see Ben White replacing Jurrien Timber at right-back, and Cristhian Mosquera potentially getting another start. Ethan Nwaneri and Myles Lewis-Skelly are also hoping for opportunities. Bukayo Saka, who is building up his fitness after a hamstring injury, is expected to start on the right flank. Viktor Gyokeres is likely to lead the attack, with Gabriel Martinelli potentially starting on the left flank. Ødegaard is also expected to get minutes.

Olympiacos enters the match following a 0-0 draw against Pafos in their opening Champions League game. They are currently leading the Greek Super League. The Greek side will likely be without Roman Yaremchuk due to a calf injury and Lorenzo Scipioni, who is recovering from a knee issue.

Historically, Arsenal and Olympiacos have an equal record, with five wins each in their ten previous encounters. Olympiacos knocked Arsenal out of the Europa League in 2021.
