QPR boss Harry Redknapp says Chelsea will be making a "big mistake" in allowing Frank Lampard to come off contract. Redknapp takes his rock-bottom QPR to Stamford Bridge for tonight's white-hot West London derby.

And he said: "I personally think it would be a big mistake to let Frank go.

"We saw the other day when he scored two terrific goals at Everton that he's still a top player.

"Where can you get a goalscoring midfielder like Frank these days? There are not many around."
