Overview

• Kickoff is 8:00pm BST at the Emirates, with live coverage in the UK on TNT Sports 1 and streaming on discovery+.
• Arsenal enter on wins over Athletic Club (2-0 away) and Newcastle (2-1), with William Saliba set to start and Martin Ødegaard back to fitness; Kai Havertz, Gabriel Jesus, Noni Madueke and Piero Hincapié remain out.
• Olympiacos lead the Greek Super League and drew 0-0 with 10-man Pafos in their UCL opener, but they are on a 10-match losing streak in Champions League group-stage away games.
• Despite Arsenal’s favoritism, Olympiacos have won on each of their last three visits to the Emirates, and the all-time European meetings are level at six wins apiece.
• General admission is effectively limited to members via the club resale, with hospitality packages still available through Seat Unique at around £299.
