Djourou insists the 61-year-old French coach continues to move the club in the right direction.
"We are always so close to winning and we were missing a little thing," Djourou said. "People say it is players or people say it is experience, but then who really knows?
"I think that we have experience because the players have been together for a long time.
"What is the real story behind it? I couldn't really tell you, but what I can say is that I think the way Arsene Wenger builds this team is the right way."
