Jose Mourinho has dropped fresh hints he could be heading for the Real Madrid exit by only publicly committing to the Spanish champions until the end of the season.
Despite being under contract with Madrid until 2016, Mourinho has done little to dispute speculation that he could be back next season at Chelsea after interim manager Rafa Benitez departs.
Mourinho left Chelsea in 2007 after three trophy-filled years.
Speaking in London on Tuesday, Mourinho said: "One day naturally I have to be back ... Chelsea is in my heart as Inter (Milan) is. One day I have to be back.''
Mourinho, who joined Madrid in 2010 after two years at Inter, added on Sky Sports News television that he is "very committed with ambitions for the club for the rest of the season.''
