Argentina have named Daniel Hourcade as their coach for the Pumas' tour of Europe next month in the November Internationals.
Should his trial period be a success, the UAR hope to keep Hourcade in the role until the 2015 Rugby World Cup in England.
Hourcade, who has just steered Argentina's second-string Jaguars to a fourth successive Americas Rugby championship title in Canada, replaces Santiago Phelan - who quit on Monday after six years in charge.
Phelan was present to make his resignation official at a news conference at Argentine Rugby Union (UAR) headquarters in the Buenos Aires suburb of Martinez.
The Pumas open their European tour with a demanding test against England at Twickenham on November 9, before facing Wales and Italy on the following two Saturdays.
