Arsenal struggled to secure a goalless draw against Atalanta in their Champions League opener despite David Raya's outstanding double save, first denying a penalty from Mateo Retegui and then the rebound. Mikel Arteta's side lacked creativity in attack and failed to capitalize on their early dominance, with Gabriel Martinelli missing a key opportunity to score. The game served as a reminder of Arsenal's ongoing challenges, particularly in the absence of captain Martin Ødegaard due to injury. With a crucial match against Manchester City looming, Arteta will need his team to elevate their performance significantly. The match atmosphere was intense, with Atalanta showing resilience after their recent Europa League success. Overall, while the point gained may be beneficial, Arsenal's display highlighted areas needing improvement ahead of upcoming fixtures.
