"I have always expressed my desire to stay at the club," said Lampard, in central London to promote Frank TV on the Orange mobile phone network.
"Unfortunately we have had problems with the negotiations. They have gone on a long time.
"My intention is to stay. I have got two years left on my contract.
"I want to stay for the rest of my career. It is as simple as that.
"I hope it gets sorted and that it gets sorted soon, at the end of the season, or the next time [we talk] - and the club know that.
"The club know my intentions, and it is certainly not a money issue.
"Some figures get banded about, inflated figures, maybe that is done on purpose - but a lot of that is not true.
"Certainly the issues I have got with the club are not to do with money.
"This is going to be my last contract, which will finish my career, so I want to get it right."
Lampard - who has often been linked with a move to Barcelona - believes it is better to delay discussions, rather than risk him losing focus for the new campaign.
The England midfielder continued: "That is why I said to the club I did not want to keep talking backwards and forwards now, because at the end of last season, it was on my mind and it does not help.
"That is not an excuse, but it does not help.
"I did not enjoy that."
Lampard maintained: "All I want to get clear out there that my intention is to stay. I want to stay, and I love the club.
"Hopefully I will stay for the rest of my career."
