The 38-year-old has been without a club since leaving Everton at the end of last season, bringing an end to a 17-year association with the Merseyside club. He has now linked up with Ireland ahead of their Nations League fixtures against Austria and Kosovo, taking on responsibilities that combine training with the players and supporting the coaching staff.
Ireland manager Heimir Hallgrímsson explained that Coleman's experience and leadership would be valuable to the squad, while also expressing a hope that the arrangement might encourage him to continue playing.
“He is going to do the sessions with the players, but he is going to be in a leadership role and supportive role with us as coaches.
“Hopefully that will get him to start playing again. That's our aim, to try to push him to continue playing.
“He has expressed that he wants to do that. We need to see where he is at. He hasn't done team training for some period now, so we need to see where he is at.”
Coleman has not been included in Ireland's 24-man playing squad for the two matches, but Hallgrímsson has not completely ruled out the possibility of using him if circumstances change. His fitness and lack of recent competitive football mean that any return to the pitch would need to be assessed carefully.
The former Everton captain has made 81 appearances for Ireland and remains a highly respected figure within the national set-up. Hallgrímsson believes his professionalism and experience can benefit younger players, even if his future as an active footballer remains uncertain.
Coleman made 433 appearances for Everton after joining the club in 2009. He was offered a coaching position by former manager David Moyes before departing this summer, but has yet to make a final decision about the next stage of his career.
Speaking on The Overlap Fan Debate, Coleman admitted that his thoughts have increasingly turned towards retirement as he has spent more time away from the demands of professional football.
“I had hopes and ambitions of maybe possibly staying playing on,” he said.
However, time with his family has helped him become more comfortable with the prospect of ending his playing career.
“The longer I've been off and the more I've been around the family, we've been back home for Halloween break with the kids, the more I'm content with what I'm doing at the minute.”
Asked whether he was officially retiring, Coleman stopped short of making a definitive announcement.
“I don't want to completely draw a line in the sand, as I said I've been keeping fit. But it's edging towards that way – and happily as well.
“Regarding what's next, I've been enjoying family time. I'm doing this [punditry] now and seeing if I enjoy it and see how it goes.”
His involvement with Ireland could provide an indication of what comes next, although Hallgrímsson is still hopeful that Coleman might find a club and continue his playing career. For now, the hybrid arrangement allows the veteran defender to remain close to the game while exploring a possible transition into coaching.
