Chelsea manager Jose Mourinho has signed a new four-year deal at the Stamford Bridge club.
The new deal will keep the 52-year-old in his post until at least 2019.
The Portuguese, who had previously been in charge from 2004-2007, rejoined in 2013 on a four-year deal, leading the Blues to the Premier League title and the Capital One Cup last season.
"I said when I returned here that I have a special feeling for this club and nothing changed," he said.
"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.
"It is the club closest to my heart and I am very happy to know I will be staying here for a long time."
Mourinho has the best win rate (69%) of any manager to have taken charge of 15 or more Premier League games and will lead his side out in their season opener against Swansea on Saturday at 17:30 BST.
Last season, Chelsea were the only club in all four divisions to remain unbeaten at home, winning the title with three matches to spare.
Ex-England striker Alan Shearer said on BBC Radio 5 live: "He's the best manager. He makes up points. If Mourinho was in charge of any of the top four, I would put them favourites to win the title."
