The former Barcelona man has been a stand-out element of Arsene Wenger's side in recent weeks, and England international Oxlade-Chamberlain has praised the Chilean's character as well as his skill.
"It's hard not to be able to learn from someone who's been at the clubs that he has," Oxlade-Chamberlain told the club's official website. "Not just that - his ability on the ball is second to none and you can always pick up little things.
"He's an attacking player like I am and he goes past players like I try to. I can always learn from a player like him. The work he does up front is something that everyone can definitely learn from as well.
"He's been a great character in the dressing room. He doesn't speak the best English just yet but he's keen to learn and he wants to be involved and around everyone. That's not just the Spanish lads, that's the English lads and the French boys as well."
Arsene Wenger recently likened Sanchez to former Arsenal target Luis Suarez.
