The 74-year-old believes his team had the better of the play at the Cardiff City Stadium but hinted at his disappointment at their lack of cutting edge in front of goalRepublic of Ireland boss Giovanni Trapattoni was pleased with his side's performance during Wednesday's 0-0 draw with Wales, but thinks they "deserved" to win the game.
The visitors had a number of decent chances to win the game, Shane Long blazing over an excellent first-half chance and firing straight at Boaz Myhill in the second, with Yeovil Town striker Paddy Madden also going close on his first cap.
However it wasn't to be and the game ended goalless, with the 74-year-old indicating they would have won the match if it wasn't for a superb day at the office from the hosts' keeper.
"I am happy with the performance and I think we deserved to win," he told reporters.
"We had three or four clear chances but their goalkeeper was fantastic."
Robbie Keane was missing for Ireland but Sunderland defender John O'Shea was present to win his 90th cap for the Republic.
Ireland have defended well under their Italian boss and the clean sheet was their fifth in eight games - something the ex-Manchester United man saw as an encouraging sign going into next month's crucial World Cup qualification double-header against Sweden and Austria.
O’Shea added: "I am a little bit disappointed. We had a couple of chances to win the game but it wasn't to be.
"When you come away from home you want to keep a clean sheet and we did that, but we had a couple of chances to win it. We'll take the positives out of it."
