David Luiz has signed a new two-year contract at Chelsea.
Luiz, who recently turned 32, is in his second spell with the Blues.
His contract was due to expire at the end of the season and Chelsea have had a policy of not offering longer than one-year deals to players over the age of 32.
However, the club have extended Luiz’s contract at Stamford Bridge until 2021.
He has been a key player this season for Chelsea, who will face Arsenal in an all-London Europa League final in Baku later this month.
“I am so happy to be here and to have this opportunity to stay. I love this club and I still have the ambition of a young player,” Luiz told the club website.
“It means a lot to reach another European final, and we still have the opportunity to finish in the top three of the Premier League this season and I will continue to try to do my best to help the team.”
Chelsea director Marina Granovskaia said: “We are delighted David Luiz will be staying with the club.
“He has set the perfect example to those around him throughout the campaign and been a huge influence on and off the pitch.
“With the Europa League final still to come, we hope to finish off the season with silverware and David will be central to that success in Baku and beyond.”
