Mikel Arteta brought up a half-century of league wins as Arsenal manager on Friday night as the Gunners got their season off to a flyer with a 2-0 victory over Crystal Palace. The north Londoners dominated the opening stages at Selhurst Park and should have gone ahead inside three minutes, only for Gabriel Martinelli to blast wide. The Brazilian made amends 20 minutes later when he powered home Oleksandr Zinchenko's cross before Bukayo Saka's cross-cum-shot was deflected in by Palace defender Marc Guehi with around 10 minutes remaining.
