Arsenal tied Atalanta, Atletico Madrid completed its comeback with a late winner and 10-man Barcelona lost despite Lamine Yamal's first Champions League goal.

David Raya made a stunning double save to keep out a second-half penalty as Arsenal held Atalanta to a 0-0 draw to begin their Champions League campaign in Italy. Raya saved Mateo Retegui ’s spot-kick down low to his right and then managed to scramble across the goal-line and keep out the Atalanta forward’s header from close range.
