Jose Mourinho described himself as “the happy one” after securing his return to Chelsea but acknowledges that expectations at the club are higher than in 2004.
The 50-year-old was officially unveiled at Stamford Bridge on Monday afternoon after the Portuguese coach penned a four-year deal with the club last week.
Mourinho takes charge of the Blues following decorated spells at Inter Milan and Real Madrid after leaving Stamford Bridge by mutual consent back in 2007.
The Chelsea manager won two Premier League titles, the FA Cup and two League Cups, as well as reaching three Champions League semi-finals, in his first spell with the Blues.
And whilst Mourinho wants respect for his past achievements, he hopes to be loved for the success he plans to deliver in his second spell at Chelsea.
“I am the happy one,” Mourinho said.
“Time flies. It feels like a couple days but it was nine years ago and since then a lot of things have happened in my professional life.
“I have the same nature and the same heart and have the same emotions to football and job.”
He added: “I want to be clear, I didn’t choose to come back for my career to be a in a comfortable position because I am where the fans love me.
“I’m coming with the opposite perspective. I have more responsibilities this time because the expectation is higher, people know what I can deliver.
“I know this club has a special fanbase. We are a special club because they never forget the professionals who gave their best for the club.
“I wanted to be respected for what I did in the past, but I want to be loved for what I can do from now.
“The club knows my mentality and nature, the fans know I have come here to do my best.”
Mourinho, who has won the Champions League with Inter and Porto, also believes he is at the peak of his powers after having enjoyed spells in La Liga and Serie A.
“You have to learn from experiences,” he continued.
“In football I analyse myself everyday – as a manager, a leader. I try to improve. So, I am the same but nine years is a big difference.”
He added: “You know my history in the British and European game. I don’t feel I need a strong approach.
“I just want to be working every day. I feel I am in the best moment of my career in terms of knowledge and experience.
“I am just so sorry the pre-season doesn’t start tomorrow.”
