Conte told Chelsea’s official website: “I am very happy to have signed a new contract with Chelsea. We worked extremely hard in our first year to achieve something amazing, which I am very proud of. Now we must work even harder to stay at the top.
“The Chelsea fans have given me so much support since I arrived here one year ago and it is important we continue to succeed together.”
The new contract is an improvement upon the terms of the three-year deal the 47-year-old agreed when he joined Chelsea, meaning he is still tied to the Stamford Bridge club until the end of 2018-19.
Former Juventus and Italy head coach Conte led Chelsea to glory in his first season in England’s top flight, with the Blues finishing seven points clear of Tottenham at the summit.
