The Arsenal winger spent most of this season at the DW Stadium before an ankle injury forced him to return to North London prematurely and despite making less than a handful of Premier League appearances, was happy with his temporary stint under Roberto Martinez.
"They have a good attitude and a good philosophy for football," the Blue Samurai and Gunners youngster told the club's official website. "The manager 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."
