For all the joy that Tuesday's win over Brighton & Hove Albion brought, there was one worrying sight.
Bukayo Saka limped off the field with nine minutes to go, after assisting Alex Lacazette's winner.
So what's the latest on our youngster?
"He was limping," Mikel Arteta said. "He took a strong challenge but hopefully he will be okay.
"Today he had a difficult game in the first half because we weren’t using certain moments to generate advantages for him and other attacking players in the right way, so the game became really difficult back to goal against a back five in a really low block.
"In the second half, the moment we started to play different was an attack in a different way where they found more space and capacity to unlock the situations and their block. We created four or five big chances and he was involved in most of the them."
