Jose coached the Nerazzurri for two years from 2008 to 2010, leaving the Serie A giants having won the treble in his final season, thus still remaining a favorite among the Inter supporters.

Speaking at an event to introduce his new book, Mourinho confessed that a return to San Siro, saying:

"Every team where I coached is a chapter of my life. At Inter I spent two special years in which I experienced many emotions in a short period of time. It was an experience that ended in extraordinary fashion like at Porto, but even better. For me Inter is special. I'm not sure if I'll return, it's hard to say since I'm in the middle of my career and I could coach another 15 years, retire when I'm 67. I certainly won't stay at Chelsea the entire time, modern football doesn't allow it. So why not? One day I could return and coach Inter."
