Inter have reached an agreement with Genoa to sign Andrea Ranocchia for an undisclosed fee, with the 1.95m-tall defender to switch clubs in summer 2011.
The 22-year-old's playing licence will be held jointly between the two Serie A teams, and he will remain at Genoa for one more campaign while having an Inter contract until 2015.
A statement from Inter read: "Ranocchia will be under contract at Inter until June 30, 2015. Inter and Genoa have agreed that Andrea will remain at the Liguria club for the 2010-11 season."
Ranocchia was a Perugia trainee before making his professional bow with Arezzo in Serie B in 2006-07 and then transferring to Genoa in 2008.
The centre-back has spent the last two seasons on loan at Bari, winning promotion in his first campaign and becoming a Serie A regular last term until a knee injury in January ended his involvement.
Until then, he had been tipped for a place in Italy's FIFA World Cup squad alongside Leonardo Bonucci, who has signed for Juventus this summer, as the duo formed a solid central defensive partnership at Bari.
In a separate arrangement, Inter's Italy Under-19 striker Mattia Destro has been loaned to Genoa for one season.
Destro is currently leading Italy's line at the UEFA European U19 Championship finals in France, having top-scored in qualifying with eight goals.
