Chelsea Football Club have confirmed that manager Jose Mourinho has signed a new four-year contract.
The 52-year-old will stay at Stamford Bridge until at least 2019.
Mourinho said: "If the club is happy, I am happy. I think this is a normal thing for me to sign a new contract. It is important we have this continuity and I hope we can enjoy more success in the future - for the fans, the players and the club.
"I said when I returned here two years ago that I have a special feeling for this club and nothing changed. It is the club closest to my heart and I am very happy to know I will be staying here for a long time."
Club director Marina Granovskaia added: "We are very happy that Jose has committed four more years to the club. Since his arrival two years ago he has carefully developed the playing squad and brought trophies to Stamford Bridge. We look forward to the next four years and the continued success of the team."
The Special One led the west London club to the Premier League title and Capital One Cup glory last season.
Chelsea began the defence of their league title on Saturday with a 2-2 draw against Swansea at Stanford Bridge.
