The 21-year-old is not renowned for his goalscoring ability having netted just twice in 25 games this season for the Gunners.
"I believe it's part of his development to play a bit more advanced," said the Arsenal manager. "You can always come deeper. He likes to come deep. In some games, he's more comfortable deeper.
"He's a bit in a situation like [Cesc] Fabregas was for a while. He said 'But I cannot score goals' but you could see it would come.
"He's more a team player than a goalscorer. He'll never be a goalscorer but he can be capable of scoring."
Arsenal travel to White Hart Lane on Sunday to take on Tottenham Hotpsur in the North London derby.
