David Luiz insists his new deal doesn't have to be his last at Chelsea.

At 32, Luiz has become one of the dressing-room leaders, which was recognised when he was handed new terms earlier this month.

He told the Daily Mail: "I want to play at a high level.

"I can say I want to play football until I'm 100, but I want to continue at a high level, so I have to look after myself, have discipline and work every single day. I want to play for Chelsea and try to win big titles.

"I have two more years on my contract, but maybe I can stay for five more. We don't know."
