Simon Kjaer's future at Palermo is set to be decided next month.
Manchester United, Manchester City, Chelsea, Liverpool and Juventus are all chasing the Denmark international, whose contract carries a foreign buyout clause of €12 million.
Everything should be decided in a matter of weeks, when Palermo president Maurizio Zamparini is due to meet with Kjaer's parent to discuss whether the defender should stay in Sicily or be cashed in during the summer.
