The 29-year-old England international midfielder's current contract is due to expire in the summer of 2009 and he has been regularly linked with a move away from Stamford Bridge.
He told the London Evening Standard: "I've been approached a few times by the club saying they are going to come to me with something and they haven't.
"That means they're saying they will have to wait until the summer and I don't really know what that means.
"I said at the beginning of the season I didn't want to talk about my contract because I wanted to concentrate on my football.
"They have made contact but it hasn't been with any news. They've been saying that something is going to happen but if we wait until the summer and nothing happens, then I've got a year left which is not a position I want to be in."
Lampard, who became the first Premier League midfielder to score four goals in one game in the 6-1 thrashing of Derby, is keen for his future to be resolved.
He added: "I've made it very clear I want to stay here and I want to know what's going on. I love playing for this club, I'm enjoying the greatest days of my career.
. "Every time I run out for the club I don't think about the contract but when I am at home I would like it to be sorted out.
"It's dragged on this season and that's not ideal for me."
