The French striker will be playing for MLS side New York Red Bulls against Arsenal on July 31 as part of the pre-season tournament.
"He's been a great influence to me so it will be nice to see his face," the 22-year-old told Arsenal's official website.
"Thierry has always given me advice, telling me just to enjoy my football and not believe what people say about you," he added. "He told me just to go out and play my football and not worry about the hype."
The Gunners are currently in Germany, where they will play FC Cologne on July 23 before the start of the Emirates Cup on July 30.
