Napoli have announced the signing of Real Madrid winger Jose Callejon.

Callejon travelled to Italy earlier this week to undergo his medical and the 26-year-old has now put pen to paper on a four-year contract with Rafael Benitez's side.

Napoli said in a statement on their website: "Napoli announce the outright purchase of Jose Maria Callejon, the 26-year-old forward who comes from Real Madrid."
