Ireland’s recent win over Bulgaria and draw against Switzerland during the last international break has seen them climb four places to 28th in the FIFA World Rankings.
The Boys in Green continued their unbeaten start to life under Mick McCarthy with a strong 1-1 draw against group favourites Switzerland at the Aviva, before a 3-1 friendly victory over Bulgaria a few days later.
Their good results have seen them leapfrog Tunisia, Slovakia and Romania as well as neighbours Northern Ireland who slip down four places to 33rd in the world.
Wales also saw themselves jump one spot from 24th to joint 23rd alongside Iran while Scotland’s recent defeats to both Russia and Belgium has seen them drop four places and out of the world’s top 50- to 52nd.
Elsewhere, Belgium remain at the top of the rankings while France have overtaken Brazil in second with England remaining in fourth spot.
The rest of the top ten is made up of Portugal, Uruguay, Spain, Croatia, Colombia and Argentina.
Ireland face two difficult away games against Georgia and Switzerland coming up over the next month with their opponents sitting in 91st and 11th in the rankings respectively.
Denmark, who the Boys in Green will face in their final group game at the Aviva Stadium in November have dropped a spot from 13th to 14th in the world.
