The Norwich City frontman scored as his side claimed a 2-0 win in their qualifier against Greece this evening.
Ireland have now won their opening three matches in qualifying, and Lafferty sees no reason why they can't reach the European Championships for the first time in their history.
"I'm lost for words," he told Sky Sports News. "The lads worked hard all week. We got a good result against the Faroes.
"We knew it would be a tough game. We believe in ourselves. Every single player believes we can qualify for the Euros and this is a massive statement that we have sent out. We're top of the group and we'll sit there at the end of the year."
Ireland are on top of Group F with nine points.
