The Vietnam national football team.
Vietnam's fall was attributed to not participating in any international matches in the first six months of the year.
At present, the national team is taking their journey to the 2014 FIFA World Cup Asian Zone qualifying round and earned a 6-0 victory over Macau (China) on June 29. If they continue to play well, Vietnam is very likely to improve their position in the FIFA rankings for July.
As for other Southeast Asian teams, Thailand dropped three places to stand at 120 while Indonesia also fell two spots to rank 132. Singapore, Malaysia and the Philippines are placed at 142, 144 and 159, respectively.
Japan, Australia and the Republic of Korea are still top the list in Asia.
In the world's top ten, Mexico marked major progress this month, jumping 19 places to stand in the 9th position after winning the Concacaf Gold Cup.
Spain and the Netherlands still retained their first two places, followed by Germany, Great Britain, Brazil and Italy.
