Antonio Conte will have to make do without the services of defender Giorgio Chiellini in Juventus ‘ Coppa Italia final against Napoli on May 20. The centre-back picked up an injury in the Old Lady’s 3-1 Serie A win over Atalanta on Sunday afternoon, and was forced to leave the pitch after 88 minutes of play due to the physical problems. It is not yet known how long Chiellini will be out of action for due to the thigh injury, but Conte has confirmed that the defender will definitely miss the cup final against Napoli. “It was a thigh twinge and he will certainly be out of the Coppa Italia Final, but needs more tests,” the Juventus coach commented on Chiellini’s injury. The 27-year-old defender was included in Italy’s provisional squad for Euro 2012, and national team coach Cesare Prandelli will be closely monitoring Chiellini’s fitness.
