Debuchy has rebuilt his career at St Etienne, where he arrived in January from the Gunners. Such has been his impact, Debuchy is now a late chance to make France's World Cup squad.
Digne said: "Debuchy? For me, this is an example, a great player.
"He has an incredible mind. He showed that by having regularity and fewer injuries, he does a great job. He is complete, he defends well, he attacks well, and he is hard on the man. A modern fullback must be able to defend well and project forward."
