FIFA rankings: Socceroos hit their first century as Japan emerges as Asia's top side His critics grow louder every game, but Socceroos coach Ange Postecoglou has called on the Aussie public to keep the faith. Massimo Luongo faces up to Japan's Yasuyuki Konno earlier this month. THE Socceroos have reached their first century. Just six weeks out from their Asian Cup opener, Ange Postecoglou's men have slipped to 102 in the FIFA rankings. It's hardly a surprising scenario considering their recent results but it's still sure to sting ahead of the January 9 tournament opener against Kuwait in Melbourne. Australia will enter the three-week tournament as the 10th ranked team in Asia, dropping eight spots from their previous low last month of 94 and are now sandwiched between Belarus and Macedonia. The Socceroos have slipped out of the top 100 of the FIFA rankings for the first time, with the loss to Japan seeing them plummet to 102. Japan, who beat Australia in Osaka earlier this month, is the new number one side is Asia even though they dropped one spot to 53. Iran, who fell five spots, to 56 are second. Of Australia's Asian Cup group rivals, South Korea are at 69, Oman at 96 and Kuwait are 123. Germany still leads the overall rankings. The World Cup winners stayed ahead of Argentina, Colombia, Belgium and the Netherlands in an unchanged top five. Further down, the Faeroe Islands climbed 82 places to No. 105 - just three places behind the Socceroos - after beating Greece 1-0 in a European Championship qualifier. Perennial last-place San Marino climbed 28 to No. 180 after a 0-0 draw against Estonia ended a 61-match losing run. Brazil remains at No. 6 despite a six-match winning streak since the World Cup. Wins in Euro 2016 qualifying moved No. 13 England up seven, No. 15 Romania up six and No. 17 Czech Republic up five. Costa Rica tops CONCACAF nations at No. 16, while the United States dropped five places to 28th. Germany (1), 2. Argentina (2), 3. Colombia (3), 4. Belgium (4), 5. Netherlands (5), 6. Brazil (6), 7. Portugal (9), (tie) France (7), 9. Spain (10), 10. Uruguay (8), 11. Italy (11), Switzerland (12), 13. England (20), 14. Chile (13), 15. Romania (21), 16. Costa Rica (16), 17. Czech Republic (22), 18.
