Real Madrid coach Jose Mourinho has conceded that he has not made plans for when he eventually leaves the club.
After helping Los Blancos to the Liga title last season, the Portuguese became the first trainer in history to win the domestic league in Italy, England and Spain.
Mourinho revealed that his hunger to constantly improve is the key to his unprecedented success in football.
"From an early age I knew that to progress in my career I had to go to other countries. I knew I needed to travel, to meet new challenges in order to grow," Mourinho said to Ronda Ibera Magazine.
"When I started travelling, I aimed for England, Italy and Spain. When I finish up here at Real Madrid, I do not know which path my career will take.
"I'm in a constant struggle with myself. I always try to be the best. More and more, however, I am thinking about others and this is serving me well.
"It is increasingly difficult to coach today. A trainer today cannot be the same as he was 10, 20 or 30 years ago.
"It is an evolving profession. Obligations of a coach go far beyond choosing 11 players, teaching tactics or making changes."
Mourinho then went on to discuss how football has affected his personal life, and spoke about the sacrifices he had to make to reach the top.
"My son cannot go to college without others knowing who he is. My wife has to tell me to stay in the car while she goes shopping in a store.
"This is the price I have to pay to practice the profession that I love. I have always been linked to football, from the day I was born. I am nearing the age of 50 now, a round number with lots of meaning.
"My city is preparing me a tribute and if I look back, you will have to allow for a smile on my face," he concluded.
