Jose Mourinho: "I'll prove to Chelsea supporters I'm still special one."

Jose Mourinho wants to start from "ground zero" at Chelsea and prove himself to supporters for a second time.

Mourinho signed a four-year deal on Monday to return to Stamford Bridge and immediately told fans he was coming back as a fan, not just as a manager.

But the Portuguese will not fall back on past glories as he aims to build a side to rival his title-winning teams of 2005 and 2006.

He said: "I am not coming here to sleep on what I did in the past and be comfortable just because we have a great feeling and we have a great relation, I am not that kind of person and professional.

"I am very demanding of myself, I need of course the fans' support, but I want to start from ground zero.

Mourinho is yet to remain at a single club for more than three full seasons but, at the age of 50, he hinted he may be ready to lay down roots in west London.

"I am the same," he said. "Physically the same, but every day you have to think about yourself and about evolution.
