Keith Fahey was so shocked to score his first goal for the Republic of Ireland in Armenia that he did not know what to do.[LNB] The 27-year-old's late winner on Friday night launched the nation's Euro 2012 campaign with the victory for which they had hoped.[LNB]It was Fahey's first goal since his effort for Birmingham against Reading on the day they were promoted to the Premier League in May last year, and he was at a loss as how to celebrate as his team-mates mobbed him.[LNB]He said: "I didn't know what to do. I hadn't scored for about a year and a couple of months since the promotion day, so it was a great way to get it.[LNB]"I was a bit shocked, to be honest. It's the thing you dream of when you are a kid - even not so long ago, it was a dream for me to play for Ireland and score the winning goal.[LNB]"But the main thing is we got the three points."[LNB]Fahey's big moment at the Yerevan Republican Stadium came 14 minutes from the end of a tight encounter and just eight minutes after he had replaced Aiden McGeady.[LNB]Robbie Keane and Kevin Doyle caused problems inside the Armenia box and when the ball broke to the substitute 15 yards out, he smashed it right-footed past keeper Roman Berezovsky to snatch the points.[LNB]Fahey said: "It was scrappy enough. The ball bounced and they were struggling to get it clear.[LNB]"I think one of them knocked out to me and I was just ready to slot it in.[LNB]"But the main thing is the three points, everyone realises that. Spain came here and struggled, so it was great to get the three points."[LNB]Fahey will now hope for more involvement against Andorra at the Aviva Stadium on Tuesday evening, although he is happy simply to be part of the Ireland set-up.[LNB]He said: 'We will see. I am just happy to be involved, so any game-time with Ireland is just brilliant."
