Argentina have risen to fourth in the FIFA world ranking, leapfrogging Brazil to become South America's top side.
Sergio Batista's side, who failed to progress further than the quarter-finals at the 2010 World Cup, have been rewarded for a 2-1 friendly victory over Portugal and reach their highest position since topping the rankings in June 2008, while Brazil lost 1-0 to France in their most recent effort to drop into fifth place - their lowest ranking in two years.
The only other change in the top ten sees Croatia move past Portugal to eighth, as Spain continue their reign in the No. 1 spot.
In Africa, Zambia return to the top 100, thanks to a 4-0 win over Swaziland, and Niger drop out to 104th. Ghana remain the top performing team in 16th, and World Cup hosts South Africa have reached their best position since 2005 in 46th.
