Mourinho is 57 and is one of the most successful coaches in modern history.
He has won trophies at FC Porto, Chelsea, Inter Milan, Real Madrid and Manchester United.
He is enjoying his time at Spurs, and admits he can see himself being a manager for a long time to come.
“There is a difference between success and a successful career,” Mourinho told reporters.
“I always believe that there is a huge difference. Success is a moment. Success can be related with your talent, but can be just the fact you are in a certain place in the right moment, in the right time.
“Another thing is a successful career, which is based on year after year after year, I always wanted that kind of career. It’s part of my DNA. I know that people probably don’t think this about myself but I consider myself a very humble person, I always try to learn, I always try to be better and this is a kind of job where experience only can make us better. I really believe today I’m much better than I was 10 or 20 years ago.
“If I love what I do, if I feel fresh, it’s motivation, it’s part of my DNA, if I change probably a little bit of my profile – and at this moment I think much more about others than myself – I always like to take players into a different dimension.
“I’m a 57-year-old, very young in relation to my job, so I wouldn’t be surprised if I have 10-15 years ahead of me
