Ryo was restricted to seven appearances for Wigan but he has taken plenty of positives from his time with the Latics - and he hopes they win their battle for Premier League survival.
"They have a good attitude and a good philosophy for football," Ryo told Arsenal Player.
"The manager [Roberto Martinez] is a very good man and it was a very good experience for me. Most of the time I was injured. I couldn't play a lot of games and I couldn't show my quality. It was disappointing for me but I'm so appreciative to the Wigan supporters, the Wigan manager and the Wigan players. It was a very good experience.
"Being there helped me to grow up. As a person, I'm growing up every day. When I was at Wigan the training was very good and the people are very kind so I got some good experience there. I feel I'm improving but I need to keep working hard."
