The Boys in Green suffered a catastrophic blow to their chances of World Cup qualification after losing at home to Sweden and the Italian is pessimistic about his future as boss
While qualification remains a possibility, the Boys in Green were dealt a major blow to their chances as goals from Johan Elmander and Anders Svensson ensured a 2-1 victory for Sweden at the Aviva Stadium.
Ireland face Austria in Vienna on Tuesday, knowing they must pick up three points, and Trapattoni, who has been manager of Ireland since 2008, admitted that he did not expect his tenure to last much longer.
"I don't expect, after this campaign, to go up again [with Ireland] in the future," the Italian told the media. "But after five years I think we have achieved a good result. We have changed the team, improved the ranking [sic], we have moved on players and discovered many others."
Trapattoni guided Ireland to their first major tournament in 10 years when they qualified for Euro 2012 last year and the 74-year-old was keen to emphasis this achievement, but conceded that the result against Sweden impacted severely on his hopes for the Boys in Greeb.
"In France [2010 World Cup playoff], the first time, you know, we deserved to go through. Then we achieved qualification [for Euro 2012]," he said.
"Obviously I thought until yesterday that we could also qualify. Now, maybe, the third position could be also a good result for us."
The Republic of Ireland face Group C rivals Austria in the Ernst Happel Stadion on Tuesday September 10. Kick off 19:45 BST.
