Sunderland have completed the signing of American striker Jozy Altidore from Dutch side AZ Alkmaar on a four-year deal for an undisclosed fee.
The 23-year-old arrived on Wearside on Monday to complete a medical and he has now become manager Paolo Di Canio's sixth signing of the summer.
The striker agreed a permanent move to AZ in July 2011 and finished his first campaign in Holland with a haul of 22 goals in all competitions before adding 23 goals for the 2012-13 Eredivisie season, helping the club to a first KNVB Cup in 31 years.
Altidore has also scored 17 goals in 60 appearances for his country after making his senior debut in 2007.
Having failed to score since November 2011, he ended a lengthy goal drought in an international friendly victory over Germany in Washington DC last month.
He joins goalkeeper Vito Mannone, defenders Valentin Roberge and Modibo Diakite, midfielder Cabral and winger David Moberg Karlsson as part of Di Canio's new-look squad at the Stadium of Light and the club confirmed he is expected to join his new team-mates at their training camp in Italy.
