Boulogne gave the midfielder his first contract when he was 19 after dazzling coaches at a trial.
Boulogne general director Nicolas Durand told The Sun: “Ribery is a big hero in Boulogne because he was born here and played for the club.
“His dad lives near the training ground and watches our games — so we named a stand after him.
“Franck has gone on to become a big star since he left us in 2002 — but we may well be naming a stand after N'Golo if he continues the way he is.
“It's incredible to think N'Golo was playing for us just three years ago in front of crowds of 2,000.
“Now he's about to become a Premier League champion and will be playing in next season's Champions League."
