PARIS (AFP) - Germany have moved up to second behind Argentina as Belgium dropped out of the top three in the latest Fifa men's world football rankings released on Thursday.

A pair of 2018 World Cup qualifier wins against Czech Republic and Northern Ireland lifted world champions Germany up one spot, with Brazil also up one to third.

Former world No. 1 side Belgium are on the drift, down two to fourth and out of the top three for the first time since March 2015.

Spain, who beat Belgium in a friendly last month, are back in the top 10 while Euro 2016 sensations Wales slid one place to 11th.

In Asia, a strong 2018 World Cup qualifying run lifted the continent's highest-placed side Iran 10 places to 27th.

Singapore, under caretaker national coach V. Sundramoorthy, plunged 16 spots to a record-low 171st position, after drawing 0-0 with Malaysia at home in the Causeway Challenge and losing 0-2 to Hong Kong away this month.

This is six places below their previous-worse 165th in 2013 under then coach Bernd Stange.

The Lions are seventh in Asean, behind the Philippines (124th), Vietnam (136th), Thailand (146th), Myanmar (156th), Malaysia (164th) and Cambodia (joint 167th).

Fifa rankings (209 teams): 1 Argentina. 2 Germany. 3 Brazil. 4 Belgium. 5 Colombia. 6 Chile. 7 France. 8 Portugal. 9 Uruguay. 10 Spain.
