The Real Madrid boss was in the capital after having attended Brazil's game with Russia at Stamford Bridge on Monday evening.
Mourinho is widely expected to leave Real this summer, and suggested last week that he was ready to return to one of his former jobs, which many people took as a hint he would be back at Chelsea.
Speaking exclusively to Sky Sports News, he admitted he still loves English football and confirmed his passion for Chelsea remains.
"In this moment, I am completely independent of talks and speculations, and people who know me, know me well enough that I think about my job at Real Madrid," Mourinho said.
He joked that the current freezing weather conditions in England was not enough to put him off.
"I cannot deny that, despite this weather, I love it here, and as I said I have a house and I have big emotional connections with Chelsea and one day I think naturally I will have to be back to English football, or to Chelsea or to another club.
"Of course, Chelsea means to me differently than other clubs. Chelsea is in my heart as Inter is for example.
"One day I have to be back but again it is normal that I am in London. The same way I walk in my home city in Portugal, people see that as normal and this is normal, the same thing is normal when I am in London."
Also linked with the Manchester United and Manchester City roles, Mourinho does not expect either of those jobs to be available any time soon.
"I think Manchester is Sir Alex's kingdom and I would love that job to be his job forever, and for many more years and the other chair is Roberto with a contract," he added.
"He was champion two years ago so I don't think there is a move over there and I hope everything goes well for everyone. Even Benitez, I hope it goes well for him and I wish the same for them as me for it to go well."
Mourinho insists that his presence in London, which is regular, should not be seen as a sign of his imminent arrival, though.
"You know, there is a lot of talk but I think people has to understand that I can be in London very often, because we have a house here and I love it here and our daughter is coming to study in London and being in London should be seen as a normal thing for us," he said.
"But every time I come and people see me shopping, people start immediately making connections about a return and I feel it a little bit because I say every day I love it here and I have a fantastic time, and that I will return one day so, to be fair, I give a little contribution to the speculation.
"But at the end of the day I am in Madrid and very committed with ambitions for the club for the rest of the season.
"We are in the last eight of the Champions League and we have a final against our rivals Atletico Madrid.
"People who know me know I am professional and that in this moment I only think of Real. "
