Italy's Under-21 captain Luca Caldirola has signed a four-year deal with Bundesliga side Werder Bremen from Inter Milan, the north German team confirmed.
The 22-year-old centre-back, has been brought in to replace Greek defender Sokratis, who recently joined Borussia Dortmund.
"Luca is a very interesting player, despite his young age he has plenty of experience and has shown his leadership qualities at his previous clubs," said Thomas Eichin, Bremen's Director of Sport. "He has good technique, a good eye and is creative in an open game."
Caldirola's Italy U-21 side finished second to Spain in the recent UEFA European Championships and his deal to Bremen is worth around €2.5m ($3.25m USD, £2.1m) having spent last season on loan at Brescia.
