Chelsea manager Jose Mourinho has inked a new four-year contract extension that will keep him at Stamford Bridge until June 2019.
Mourinho, who guided Chelsea to Capital One Cup glory and a first Premier League title in five years last season, signed the new deal just a day before his side's 2015/16 season opener against Swansea.
"If the club is happy, I am happy. I think this is a normal thing for me to sign a new contract," Mourinho told the club's website. "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."
Chelsea 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."
This is Mourinho's second spell with Chelsea, having previously had a stint as Blues' manager from June 2004 to September 2007, during which time he led the London outfit to consecutive Premier League titles in his first two seasons. By the end of his tenure, Mourinho had won every domestic cup on offer.
After his first tenure with Chelsea, Mourinho joined Inter Milan in June 2008 before being appointed as Real Madrid's manager in May 2010. Mourinho returned to Stamford Bridge in June 2013.
