Mikel Arteta admitted David Raya ’s astonishing double save against Atalanta was the best he has seen in his career. Raya ensured Arsenal avoided defeat in their Champions League opener by keeping out a penalty and the rebound from Italy striker Mateo Retegui.

Mikel Arteta praised Riccardo Calafiori after the summer signing made an impressive cameo appearance as a second half substitute against Atalanta. The Italy international has had to bide his time for opportunities since his arrival from Bologna in the summer and missed the north London derby as a result of the calf injury he picked up playing for his country a fortnight ago.
