Arteta today spoke glowingly of Nketiah, who has started the season in excellent form with goals against West Ham and Leicester.
It has led to suggestions the 21-year-old, who has 12 goals in 10 matches for England under-21s, might earn a first call-up to Gareth Southgate's senior squad.
Arteta said: "Obviously if he keeps performing in the way he has been with us in the last few months he will have a really good chance.
"I think culturally, England and the actual manager are really brave with young kids.
"It's up to them, they have to be consistent and keep doing what they're doing at club level and then that opportunity will come in a natural way."
