Arsenal's first home match in the 2026-27 Champions League will also mark their first encounter with Lille, who visit the Emirates for a group stage clash on Tuesday. Mikel Arteta's team secured a narrow 1-0 victory against Napoli in their opening match, while Lille faced disappointment, losing 3-2 at home to Real Betis despite having a player sent off. Arsenal has been on a remarkable run in the Champions League, winning 13 consecutive matches since their 1-0 defeat to Inter Milan in November 2024. Their latest victory came in Naples, where Martin Odegaard scored the decisive goal just 15 minutes before the end, although the team dominated the game, achieving a record 4.05 Expected Goals in a Champions League match. With a strong desire to achieve continental success, Arteta's squad can draw confidence from their impressive record of only two losses in their last 31 group stage matches across all UEFA competitions. Additionally, they have scored three or more goals in five of their last six home games at this level. The reigning Premier League champions recently returned to the Emirates, where they came from behind to defeat Leeds United 2-1, ending Leeds' unbeaten run in the league. However, Arteta had to make tactical changes after a lackluster first hour of play. James Justin's opening goal against Arsenal highlighted a troubling trend in the team's defense, as they have conceded six goals in their last three matches across all competitions, following just one goal conceded in their first six games of the season. Lille, on the other hand, will be looking to address their defensive issues after a chaotic loss to Real Betis, where they twice took the lead but ultimately dropped points.
