Mourinho won the Premier League twice in three years at Stamford Bridge, ending the club's 50-year wait for the title.

He also lifted the Carling Cup twice and the FA Cup before being fired last September following a long power struggle with the board.

He will be assured a hero's welcome if he returns with his new team.

The Portuguese has taken charge of Italian champions Inter Milan this summer with a brief to win the Champions League again.

Mourinho added: "This is a great experience for me after eight months away from football. It is fantastic to be back. I'm still in love with English football. I still feel a big relationship with Chelsea."
