The Philippines is the highest-ranking country in the Southeast Asian region, followed by Vietnam (130), Thailand (137) and Myanmar (152).
In August 2017, the Super Eagles were ranked 38th best in the World by Federation Internationale de Football Association, but Gernot Rohr's men have now dropped to 44th best in the world.
That was not enough to take them upwards, as they are now ranked fifth in Africa, according to the world football governing body. A position formally occupied by Cameroon, who just like the Eagles, dropped in the rankings.
Belgium, Poland, Switzerland, France, Chile and Colombia round off the top 10.
The Philippines remains the top-ranked football nation in Southeast Asia, with Vietnam coming in second at 130th in the world. After a disappointing 2017 - a year which has seen chances of World Cup qualification dip from promising to hanging by fingernails - Ireland have dropped 11 places.
The former African champions rose from 96th to 78th following back-to-back victories over formidable Algeria in the World Cup qualifiers.
