The winger has returned from his injury-plagued loan spell at Wigan Athletic.
"It's great to hear that [kind of compliment] and I'm so appreciative," Ryo told Arsenal Player. "I'm always ready to play for Arsenal. It's my dream to play for Arsenal. First of all, I have to recover as soon as possible. Then I want to show my quality when I get fit.
"My ankle is getting better so I'm comfortable at the moment. My target is to be there [on the Asia tour] so I think I can be fit in pre-season."
