The FAI has confirmed that Keith Andrews, Damien Duff and Alan Kelly will all be coaches in Stephen Kenny's backroom team.
Kenny was appointed as the new senior men's team manager on Sunday, taking over immediately from Mick McCarthy.
Kenny's step up to the senior job means that Jim Crawford has been promoted to manager of the Ireland under-21 side. John O'Shea will be his assistant.
Andrews joins Kenny in the move up from the under-21s. Duff, currently a coach with Celtic, will make a move to his new role on August 1st.
Alan Kelly continues as goalkeeping coach, having worked previously in the role with Stephen Staunton, Giovanni Trapattoni and Mick McCarthy.
There is no place, as of yet, for Robbie Keane in Kenny's staff. Keane was assistant to McCarthy.
Jim Crawford has worked as Stephen Kenny’s assistant manager to the Ireland Under-21 side in their European Championship campaign and will be joined in his new position by Waterford native John O’Shea, currently on the coaching staff at Reading.
Crawford and O’Shea will now look to build on Ireland’s positive start under Stephen Kenny in their bid to make the UEFA Under-21 European Championship finals for the first time.
