Sunderland have boosted their defensive options by recruiting Marcos Angeleri from Argentinian side Estudiantes de La Plata.
Manager Steve Bruce has swooped to sign the right-back for an undisclosed fee on a three-year deal.
The 27-year-old - who has three senior caps for Argentina - becomes the third South American in the Black Cats' ranks, with Paraguayans Paulo Da Silva and Cristian Riveros also hailing from the continent.
The defender missed out on selection for Diego Maradona's World Cup squad for the finals in South Africa this summer due to injury but the player has impressed Bruce enough to secure a deal.
Angeleri began his career at Primera Division side Estudiantes in 2002 and has amassed 175 appearances for the 2009 Copa Libertadores champions.
Bruce said Angeleri will provide depth to his squad, as well as additional options on the field.
He told the club's official website: "Marcos is a strong, powerful defender and will add depth to the squad.
"He is also very keen to get forward from that position so that adds an extra dimension to the side.
"He has been one of the best right full-backs in South America in recent years and has really impressed us when we've watched him."
