Another pair of scoreless matches have impacted Canada's ranking, which is down 15 spots from August.
Benito Floro's side dropped to 106th in the Sept. FIFA world rankings, a 15-spot fall from the previous list published in August.
Canada played its first pair of matches under Floro this month, drawing 0-0 and losing 1-0 against Mauritania. The games extended a woeful run in 2013 during which the Canadians have failed to win and have only scored once.
Elsewhere in CONCACAF, the USA is up six spots to 13th in the world, its highest ranking since June 2010, following wins over Bosnia-Herzegovina and Mexico that sandwiched a loss to Costa Rica. The six-place rise was the highest among teams in the top 20, and it creates an eight-place gap between the USA and Mexico, which fell one spot to 21st following a friendly win over Ivory Coast and World Cup qualifying losses to Honduras and the USA.
Spain maintains its place atop the world rankings, but it has a new top competitor, as Argentina rose two places to second overall after securing a place in Brazil next summer on Tuesday. Lionel Messi's Albiceleste are followed by Germany, Italy, Colombia, Belgium, Uruguay, Brazil, Netherlands and Croatia to round out the top 10.
