QPR's John Eustace has been appointed as assistant manager to Stephen Kenny with the Republic of Ireland, replacing Anthony Barry.
The former Coventry City, Watford and Derby County midfielder succeeds the highly-rated Barry who departed for Belgium.
Eustace joins Stephen Kenny's staff ahead of the international friendly matches against Belgium and Lithuania and will be in situ for the UEFA 2024 European Championship qualifying campaign.
The 42-year-old will remain in his existing role with QPR, which is also as assistant boss, and link up with the Ireland squad in the international windows.
Eustace said: "I'm delighted to join the Republic of Ireland coaching staff and excited to link up with the squad this week for the matches against Belgium and Lithuania.
"The opportunity to join Stephen Kenny's coaching staff is an exciting prospect and I'm looking forward to working with this young group of players."
Kenny is pleased with the successor to his previous right-hand man: "John has been assistant manager with Queens Park Rangers for four years and has established himself as an accomplished and well-respected coach.
"He is an excellent addition to the coaching team and we're looking forward to linking up for the two matches against Belgium and Lithuania, and for the season ahead."
