Coach eyes long-term success after a four-year contract in Stamford

Jose Mourinho says he has returned to Chelsea because he wants to leave a long-lasting legacy for the first time in his managerial career.

The 50-year-old Portuguese has achieved success wherever he has coached, but he has never remained with a club longer than the three years and three months he spent at Chelsea in his first spell between 2004 and 2007.
