Arsenal, last year's Champions League runners-up and current Premier League champions, face Lille at the Emirates Stadium. Mikel Arteta's side started with a seven-match winning streak before a 3-0 loss to Brighton and Hove Albion. They rebounded with a 2-1 victory over Leeds United, featuring goals from Riccardo Calafiori and Bruno Guimaraes. Lille, under new coach Davide Ancelotti, have had a positive start to their domestic campaign, including a recent win against Le Havre. However, their Champions League season began with a 3-2 home defeat to Real Betis. Key players like Eberechi Eze are expected to feature for Arsenal, while Lille will be without Ethan Mbappe due to suspension, and several others like Romain Perraud and Hamza Igamane are injured. Arsenal are heavily favored to win this encounter.
