Italy international Emanuele Giaccherini completed his move from Italian champions Juventus to Sunderland, the English Premier League club said Tuesday.
The 28-year-old, a first choice winger under current Italy coach Cesare Prandelli, has signed a four-year deal.
Juve, who have won the last two Serie A titles, said they had received £6.5 million (7.5 million euros, $10 million).
Giaccherini only made his debut for Italy after joining Juve two years ago from minnows Catania.
But he has since forced his way into the national side and featured at both Euro 2012 and last month's Confederations Cup.
He can play as a wing-back, winger, deep-lying forward or attacking midfielder.
He is the latest signing in a major overhaul of his squad by Sunderland's Italian manager Paolo Di Canio, with Valentin Roberge, Modibo Diakite, Cabral, Vito Mannone, Jozy Altidore, Duncan Watmore, David Moberg Karlsson and El-Hadji Ba also joining.
In a busy close season Simon Mignolet, Titus Bramble, Matt Kilgallon and Ahmed Elmohamady have all left the Stadium of Light.
