The Republic of Ireland have fallen two places in the latest Fifa ranking update as they look ahead to their final Euro 2016 warm-up friendlies against the Netherlands and Belarus in May.
Despite securing a victory against Switzerland and a draw against Slovakia - two teams who were ranked higher than the Boys in Green - at the end of March, Martin O'Neill's team have dropped to 31st in the newly updated table.
The drop marks Ireland's first descent in the ranking since October 2015 and they now find themselves behind the United States.
Northern Ireland, on the other hand, have gone up two places in the latest update after drawing with Wales and defeating Slovenia. Michael O'Neill's side now occupy 26th place in the table and sit ahead of Poland and Russia.
The Republic of Ireland's Euro 2016 opponents Belgium, meanwhile, have been knocked off the top of the ranking and are now second behind Argentina. Ireland's other Group E rivals Italy have dropped one place to 15th, while Sweden are now 36th after falling two spots.
Reigning world champions Germany suffered another fall, dropping one spot to fifth, while Spain fell three places and now occupy sixth. Chile have moved up two to third, while Colombia leapt four spots to fourth.
Roy Hodgson's England fell one position to 10th, while Wales tumbled seven places down the table to 24th. Scotland experienced more positive news with a rise of five places to 40th.
The next update will be announced on May 5.
