Sunderland have signed Italy international Emanuele Giaccherini from Juventus for £6.5m.
The 28-year-old midfielder, who has made 14 appearances for Italy, has agreed a four-year contract.
He played at Euro 2012 and this summer's Confederations Cup, when he scored in a 4-2 defeat by Brazil.
Giaccherini signed for Juventus in August 2011 and made 40 appearances in helping the Turin club to back-to-back Serie A titles.
After starting his career at Cesena, he had loan spells at Forli, Bellaria and Pavia before joining Juventus.
Giaccherini has also scored the fastest ever goal in the history of Italy's national side, netting after 19 seconds in a friendly against Haiti in June.
