Arsenal boss Mikel Arteta admits the future of Bukayo Saka is "in his hands".
The wing-back is locked in new contract talks, with his current deal having just over a year to run.
After victory over Southampton, Arteta said: "It's in his hands. He has a manager that has total belief in him, he has a club that really supports him and he has team-mates who adore him for who he is.
"He's such a nice boy, he's very intelligent and he's so willing to learn. He's eager to be the best, he tries to be the best every day, and you can put him in different positions and he picks it up really quickly. Every decision he makes, he takes risks.
"I think he could have produced three goals today. The maturity he shows on the pitch is really good."
