Ireland have slipped eight spots to 36th in the FIFA rankings after the 6-1 hammering by Germany in last month's World Cup qualifier.
The humiliating defeat in the Aviva Stadium has had a significant impact on Ireland’s standing with the 4-1 win over the Faroe Islands proving little consolation.
World and European champions Spain remain top of the rankings with Germany still their nearest challengers.
England have slipped a place to sixth, while Northern Ireland enjoyed a leap of 17 places thanks to the 1-1 with Portugal, moving to 100 in the standings.
Scotland, who sacked Craig Levein as manager this week, have dropped below Wales after being beaten 2-1 in their head-to-head match last month.
Scotland drifted by 14 to 70th while a 2-0 defeat in Croatia meant Wales also dropped from 57th to 66th.
