He confesses that he likes nothing better than taking his life into his own hands by riding his motorbikes through the Portuguese mountains.
Villas-Boas, 33, revealed: "My passions are outside football and I am not one of these people who are obsessed with the game.
"I have a tremendous passion for the game but I don't live and breathe it 24 hours a day.
"Some coaches like to pretend they watch everything, but I'm not like that. When it's time to switch off, I do. I don't go home and watch second division German football.
"Football is a very strenuous business and when I get the opportunity I go back to Portugal and ride my motorbikes into the mountains with the big rocks and almost kill myself!
"I have had a few crashes in my time. I broke my arm once but I feel fantastic when I am riding my bikes. Driving is adrenaline-fuelled and that's my escape, my passion.
"I have five motorbikes back home in Portugal including a couple from the Paris-Dakar Rally. I also have a couple of trials bikes and I have a shared ownership in about 12 classic cars.
"My first bike was a 350cc heavy engine Yamaha. I took my licence and drove in a national competition when I was the Porto youth coach. That was when I crashed and broke my arm.
"I'd love to take part in the Paris-Dakar rally. That's a proper endurance race, but maybe it's something for after my career."
