Republic of Ireland saw their chances of qualifying for the World Cup in Brazil recede as a result of a damaging 2-1 defeat at the hands of Sweden and now have it all to do
Robbie Keane's 60th international goal gave the hosts the lead but Johan Elmander and Anders Svensson turned it around, meaning that the Boys in Green ceded the initiative in their World Cup qualfying group.
"We started very well and took advantage in the first half," Trapattoni told RTE after the game, "but two episodes decided the match.
"They played physically. They took the two opportunities very well. They scored. They took these two opportunities. In the first half we had more shots."
Though Sweden are now three points clear of Ireland, the Italian is optimistic that his side can turn things around with a win in Vienna on Tuesday.
"We think about what we can do," he added. "At the moment, we are third. We need to win in Austria. We need a result in Germany and, after, we must beat Kazakhstan."
"I change one or two, maybe one or two [for the Austria match]. I have convinction that we had a possibility to increase our personality. Against Georgia we showed this personality and we have to have more conviction. We can't give Austria the same opportunities. We have to think about our mentality, our attitude."
