Inter Milan have come in for Napoli's Marek Hamsik, rivaling Chelsea for the Slovakia international.
Former Blues boss Jose Mourinho has made his intentions clear on attempting to sign the 22-year old who has impressed in the Serie A this season and is keen to bring him to Milan.
Chelsea boss Carlo Ancelotti has confirmed he is interested in the £17million-rated midfielder but Mourinho's enquiries to Inter president Massimo Moratti to fund a move for him must have the Blues nervous.
