The Gunners legend was named as an ambassador for The Arsenal Foundation last season and has been training at London Colney in recent weeks.
"He is still very fit and a great player and we are always happy to have him in training but he just occasionally comes in to practice," said Wenger.
"It's a great opportunity [for the young players]. He practices with the young players with the under-21 team, and I feel always there is no better education than playing players at that age with top-level players."
