Singapore are now ranked 162nd in the world according to the latest Fifa rankings released today. The current position is four places lower than from the previous rankings.
A lack of frequent friendlies and poor results in the last quarter against the likes of Hong Kong and neighbours Malaysia meant the Lions dropped to their lowest ever position since the inception of the rankings in 1993.
Hong Kong moved up six places to reach 154 while Malaysia retained their 157th position.
Singapore are ranked 30th in the AFC zone, below the likes of Nepal and Maldives, and 6th in Asean. Japan are the top ranked Asian team and Thailand have overtaken Vietnam to lead the Asean region.
Euro 2012 victors Spain retained their top position in the world rankings with Germany and England close behind. England's third place incidentally is also the highest ever for the Three Lions.
In the women's rankings, USA are the top ranked nation with Germany and Japan in second and third respectively.
The Singapore Lionesses who have been inactive since the 2011 AFF Women's Championship have moved up to 92nd in the world, up five places since the previous rankings, and 21st in the AFC zone.
The Singapore men's team will be in action on August 15 against Hong Kong at the Bishan Stadium.
