The French midfielder was discussing how his loan spells at Lorient and Freiburg helped his breakthrough.
The French midfielder is now Arsene Wenger’s first choice in the defensive role having broken through and impressed in the side last season.
Before then he had been struggling to make that breakthrough into the first team, instead spending his time on loan at the likes of Lorient, Freiburg and Charlton.
And he believes his experience doing that has been key to his development, warning the latest youngsters that despite Arsenal being a great club, it can become too much of a comfort zone for youngsters.
“It was a great learning experience, Arsenal is a great club - a massive club, but you are kind of in a comfort zone as it is such a big club, you have all the facility,” he told The Mirror.
"To go away, go abroad and see a different culture and different football helped me a lot and I came back stronger.”
"I always had belief in myself, I didn't think it would happen that quickly as I was on loan quite a few times but when I went back I always had my belief.”
The latest crop of Arsenal youngsters would do well to take Coquelin’s advice on board given how much of a success he has been.
There may have been some luck to his breakthrough last season, but he has grasped that chance with both hands and is very much a key player in their team as well.
His previous first team chances on loan have seemingly helped in that process, and perhaps more Arsenal youth products will look to head out on loan in the hope of replicating his success.
