Argentina named Daniel Hourcade as coach for the Pumas' tour of Europe and with a view to keeping him on 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 Nov. 9. They play Wales and Italy on the following two Saturdays.
