Robbie Keane was on the Shamrock Rovers bench in a voluntary coaching capacity for Sunday's pre-season friendly against Cork City.
The former Ireland striker has been coaching voluntarily with the League of Ireland Premier Division champions, as he has done previously, working alongside long-term friend and former team-mate Stephen McPhail and fellow Tallaght native Stephen Bradley.
Keane has recently worked as assistant manager at Middlesbrough alongside Jonathan Woodgate, while he was also a member of the coaching staff during Mick McCarthy's second spell as Ireland manager.
The Ireland record goalscorer is not expected to take on an official role with the Dublin club for this year's SSE Airtriticy League campaign.
New FAI chief executive Jonathan Hill confirmed on Friday that Keane was still currently employed by the association, however, he has no official role at the moment.
"Robbie remains an FAI employee", said Hill. "I haven't had the opportunity yet to sit down and talk with him, I will do that. Robbie is a legend in Irish football and I look forward to having an open and honest conversation with him about the situation.
"It hasn’t happened yet, and I am open to all different possibilities in relation to Robbie. But Robbie will tell me where he is currently, I hope, when we get the chance to chat."
