As the only manager in Premier League history ever to guide his side to an unbeaten season, Arsene Wenger is placed better than anyone to know exactly what it means to be 'Invincible'.
What qualities are required? Is there an innate sense that is needed if you are to achieve the impossible?
"Invincible is linked with a mental resilience," he says in Arsene Wenger: Invincible.
"It is something deeper, a refusal of defeat at any cost. Don't give in, ever."
Arsene Wenger: Invincible is out from today in select cinemas and on Blu-ray, DVD and Digital from November 22.
