The Portuguese believes the Blues' young squad needs a manager who will bring stability and has suggested he is ready to end his usual pattern of three-year spells
The Portuguese has won league titles as a coach in four different countries and has established a reputation for seeking new challenges every few seasons.
Upon his return to Stamford Bridge, however, Mourinho has expressed his desire to settle down in west London and guide a young squad to success more slowly.
"I am the same, physically the same, but every day you have to think about yourself, especially the manager, and about the evolution," he told Chelsea TV.
"I have the same nature but I'm much more mature with a different approach to things, I'm more ready to be in a club and stay for a long time."
Mourinho believes stability is the order of the day at Chelsea given the emergence of youth in the first-team squad in recent seasons.
"I hope so," he replied when asked if he imagined a stay longer than his usual three years. "When you look at the profile of the Chelsea squad I think it's what they need at this time.
"If you look from my time, there are around four or five boys and these are the older ones - very important for this football club and very important for the balance of the squad, but it's a young squad with a lot of talent and I think they need stability to reach a high point of their evolution and for their careers.
"They need stability, stability I hope I can give them and between me, the owner and of course the club, we have no doubts about what we want to do and the approach we want to have.
"I'm very confident I can help the team and help the boys to develop.
"I feel myself not just as the Chelsea manager, because this is the first time in my career that I've arrived at a club that I already love. Normally I love the club a couple of years after I am there.
"Of course I go to a club, I wear the shirt and I feel the shirt with the crest and I give everything I have to do it, but this is the first time where I love it already.
"To be at the same time a Chelsea fan and a Chelsea manager is a new feeling for me and it's a fantastic feeling."
