Saka has missed just 184 minutes for Arsenal during the current campaign and there have been concerns he could burn out.
The winger limped off during the Gunners’ 1-0 win over PSV on Thursday night in the Europa League due to a calf problem.
But Arteta has since been speaking about the winger and insisted he can play so much football due to his change in mentality:
“Here,” said Arteta, tapping his head, when answering how Saka has become more robust this season.
“Robustness is in your mind. How much you want it, how tough you want to be with yourself, how pushy you want to be with yourself and what you do to get to that level.
“The gym is very important but what happens in your brain I think is more important.
“I think he has a really powerful environment around him. His family, the people around him, the way he’s been raised.
“He has some important people in his life. I think there are some really good influences as well. And then everybody at the club that tries to protect him but as well challenge and push him to get to a different level.”
Arsenal are set to face off with Southampton on Sunday as they look to maintain their four-point lead atop of the Premier League.
