Arsenal secured a goalless draw against Atalanta in their Champions League opener, largely thanks to goalkeeper David Raya's remarkable double save, first stopping a penalty from Mateo Retegui and then denying the rebound. The match showcased Arsenal's defensive strength but highlighted their attacking struggles, particularly in the absence of captain Martin Odegaard due to a significant ankle injury. Despite a promising start, Arsenal managed only two shots on target and failed to capitalize on early dominance. Mikel Arteta's side will need to enhance their creativity as they prepare for a crucial match against Manchester City next. The draw marked a conservative approach from Arsenal, reflecting a cautious strategy in a challenging group stage. Atalanta, returning to the Champions League, will take encouragement from their performance despite the stalemate.
