Fifa world rankings: Republic of Ireland overtake Northern Ireland as both teams move down
Northern Ireland have fallen to 34th in the latest Fifa world rankings following back-to-back Nations League defeats
Michael O'Neill's side drop six places and are 14 spots lower than their highest ever position of 20th, which they reached last September.
The Republic of Ireland now sit ahead of their neighbours in 33rd having slipped three places.
England move up to fifth while Belgium replace France at the top.
Defeats in Austria and Bosnia have left Northern Ireland bottom of Group B3 with relegation to the third tier of Uefa's new competition looking increasingly likely.
O'Neill's team have now gone without a win in their last seven competitive fixtures, although they have defeated South Korea and Israel in friendlies.
The Republic took one point from their two Nations League fixtures this month, drawing with Denmark before falling to defeat by Wales in Dublin.
Scotland have fallen to 40th while Wales sit one place ahead of Italy in 18th.
