Ireland won yesterday 1-0 against Georgia in their World Cup qualifier. He admitted their rivals were "miles better".
He told 'BBC': "I expected Georgia to run us close. If they had a natural goalscorer in their team they could cause teams lots of problems.
"It was very difficult indeed; they had by miles the better of the first half and then we came into it.
"The players have a great desire to do well. We needed a spark at half-time and they got themselves going. We can play much better than that," he said.
