Joshua Walter "Paddy" Sloan (30 April 1920 – January 1993) was an Irish football player and manager.
 His widely travelled career took Sloan to 20 different clubs in five different countries, including Northern Ireland, England, Italy, Malta and Australia.
 As a player, his clubs included Manchester United, Arsenal and Milan.
 He was a dual Irish international footballer, playing for both Ireland teams – the IFA XI and the FAI XI.

Brian Kerr (born 3 March 1953) is an Irish football manager.
 Born in Dublin, Kerr grew up playing football and boxing.
 At the age of 13, he took his first coaching role with the Crumlin United under-11 side.
 Realising later that he didn’t have the talent to become a top player, he decided to focus on coaching.
 In 1986, he was appointed manager of the League of Ireland side St Patrick's Athletic.
 In 1992, when the club was facing liquidation, Kerr was among the investors who raised IR£82,000 to help save the club.
 In December 1996, he left St. Pat's to become the technical director of the Football Association of Ireland, but he is still idolised by the St. Pat's fans.
 He worked with the Republic of Ireland youth squads and also with the senior side.
 He was appointed as the full-time manager of the senior Ireland team on 26 January 2003.
 In 2007, Kerr became the Director of Football of St. Patrick's Athletic.
 Then, in 2009, he was confirmed as the head coach of the Faroe Islands national team.
 He left that post in October 2011.

The League of Ireland XI, more recently referred to as the "Airtricity League XI" for sponsorship reasons, is the representative team of the League of Ireland, the national association football league of the Republic of Ireland.
 For much of its history, the League of Ireland XI has effectively acted as a reserve or B team to the senior Republic of Ireland national team, providing international representative honours to home-based players.
 In fact it has played considerably more games than the actual Republic of Ireland B national football team.
 In addition to playing regular games against similar representative teams, such as the Irish League XI, the Scottish Football League XI and the Football League XI, the League of Ireland XI has also played in prestige friendlies against the full national teams of both Argentina and Brazil.
 The League of Ireland XI also represented Ireland in the qualifying stages of the 1988 Olympic Football Tournament.
 More recently a League of Ireland U-23 XI has represented the Republic of Ireland in the International Challenge Trophy.
 Meanwhile, a senior team with no age or nationality restriction regularly plays visiting club sides.
 More recently the team competed in the 2011 Dublin Super Cup
