#2 Gary Breen (2002)
Gary Breen has never played football as well in his life as he did for a few weeks in the summer of 2002. In truth, Breen was a decent defender, no more, no less, but in the 2002 World Cup, he played so well that Inter Milan were believed to have an interest in him. In the end, he signed for West Ham United, but it's not very often an Irish player is linked with a move to Serie A.
To this day, Ireland fans still sing his name at games all over the world with the song going "we all dream of a team of Gary Breens" to the tune of Yellow Submarine by The Beatles. His greatest moment was the second goal in a 3-0 win over Saudi Arabia which saw Ireland reach the last 16 where they lost on penalties to Spain.
