Chelsea manager Jose Mourinho has put pen to paper on a new four-year deal, the Premier League champions have confirmed.
The news comes on the eve of the new campaign, with the Blues one of the early favourites to secure glory once more.
Mourinho's Chelsea also won the Capital One Cup last term, in what is his second spell in charge at Stamford Bridge.
The Portuguese's new contract will keep the 52-year-old at the club until 2019 and Mourinho spoke of his happiness at signing a new deal with the west London side.
"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," Mourinho told Chelsea's official website.
"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."
Not only did Chelsea secure the title last season, but the Blues conceded the fewest goals (32) in the Premier League and were the only team in England's top four divisions to go unbeaten at home.
