Former Chelsea defender Michael Duberry has warned Frank Lampard against moving to Manchester United.

Lamp has emerged as a shock target for United manager Sir Alex Ferguson.

But Duberry told talkSPORT: "Frank Lampard can do a job for any team in the Premier League.

"He's got a lot to offer. He's a world class player, a professional and keeps himself healthy. Age is nothing but a number because he keeps himself in shape.

"He's adored at Chelsea so why he would want to go to Manchester United and ruin his legendary status at Chelsea, I don't know."
