A decision on Lampard's future won't be made until after the World Cup, but with the England international yet to sign a new deal, he has admitted that he is uncertain whether he will stay in West London.
The 35-year-old told The Sun: "I don't know if I'll be at Chelsea next season. I'd like to carry on for two or three more years but it would be good to end on a high.
"So, if that means it all ends tomorrow, I wouldn't have any regrets. You know your shelf-life, so I started to mentally prepare when I hit 30. I've been doing this for a long time, so there's a part of me that's looking forward to the future."
Lampard has scored 211 goals in 648 appearances during a 13-year spell with the Blues.
