Arsene Wenger has given some fascinating insight into his life as a football manager.
Wenger says being a professional football coach is a similar lifestyle to that of a priest.
Asked for the secret to his longevity, Wenger told Arsenal.com: "I am a specialist in masochism! (jokingly)
"It's very demanding and it's a sacrifice of your life.
"You have nothing else happening in your life. Basically you get 90 per cent aggravation and 10 per cent top satisfaction and you have to give everything in your life for that. You have to be ready for it.
"That's what I always say to all the young people who want to go into this job. 'Are you ready to sacrifice your life?'
"It's like a priest. You're a football priest."
He added: "I believe [my career has] allowed me to get to the next level as a human being, to develop my strengths in what makes a human being great as well.
"It is very demanding, but as well very interesting if you really face the challenge.
"By accepting as well, facing the reality, in an objective way, about what you have to do to get better."
