Reine-Adelaide was still with Arsenal when Wenger chose to step down at the end of last season.
He told Foot Mercato: "It was a very important moment. It touched a lot of people at Arsenal because he was there for a very long time.
"Arsène taught me a lot. I think I learned to have a big mind there. It has not always been easy. He always helped me, he always talked to me, before or after the training to tell me that I was a young player and it would happen one day or another.
"He helped me to progress as a player but also as a young man. It is important for this coach to help people become men. I do not know if he will take over a team. But I hope for him that it will happen."
