Chelsea have been told they must cool their jets over a bid for Napoli star Marek Hamsik.

The News of the World says Chelsea chiefs want to bring the young midfield dynamo to Stamford Bridge, but know no deal will be considered by Napoli in January.

Napoli president Aurelio de Laurentiis rates Hamsik in the £14 million class and knows the youngster has been unsettled after he was the victim of a carjacking outside the club's training HQ last week.
