Gerardo Martino has been hired as coach of Argentina, less than three months after leaving Spanish club Barcelona.

The Argentine Football Association says the 51-year-old Martino will replace Alejandro Sabella, who stepped down after Argentina's loss to Germany in last month's World Cup final.

It will be Martino's second coaching role with a national team, having been in charge of Paraguay from 2006-11.

Martino left Barcelona in May with one year left on his contract after the club failed to win a major trophy for the first time in six years.
