David Luiz signed a new five-year contract at Chelsea on Saturday, the club confirmed.
Brazil defender Luiz was less than two years into the five-and-a-half-year deal he penned when joining the Blues in January 2011.
But the European champions moved to tie the 25-year-old down until 2017.
"I am very happy to sign a new contract with Chelsea," Luiz told the club's official website. "It is a great club and I look forward to winning more trophies here. I want to play for a long time at the top level -- which is what playing for Chelsea means. I love everything about the club and especially the fans, who have made me very welcome and given me great support."
Luiz has become a cult figure at Chelsea since joining from Benfica in a deal worth around £25 million ($40.6 million), and helped the Blues to Champions League and FA Cup glory last season.
He has also come under fire for some of his defending, with former Manchester United defender Gary Neville famously comparing him to a player being "controlled by a 10-year-old on a PlayStation."
But that did not prevent him from being linked with Barcelona and a new contract will end that speculation for the time being.
