Frank Lampard has told Chelsea he wants his future sorted out as the club continue to stall over a new contract. The England midfielder is running out of patience over his contract situation, which could remain in limbo until the summer.

Lampard, who scored four goals in Chelsea's 6-1 demolition of Derby last night, insists he wants to stay at Stamford Bridge but is perplexed by the fact no offer has been made.

"I've been approached a few times by the club saying they are going to come to me with something and they haven't," declared Lampard. "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.

"I've made it 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."

Lampard's change of emphasis on his contract situation will throw the spotlight back on the club's plans. Coach Avram Grant refuses to talk about his contract negotiations, saying it is not his area.

Grant believes Lampard will stay but Chelsea are in danger of losing one of their biggest assets if they do not open negotiations before the end of the season.

Lampard took his goal tally for the club to an amazing 107 in almost seven years with his four-goal haul as Chelsea's victory over Derby put them right back in the title race.

They are now just five points behind leaders Arsenal with a game in hand.
