Coleman stepped down last year after Wales failed to qualify for the World Cup in Russia and has now moved on to Championship side Sunderland.
However, he insists he has no regrets about that decision, despite the fact the Black Cats are bottom of the league.
Wales have yet to name an appointment, but former players Ryan Giggs and Craig Bellamy are being linked with the post.
Coleman insists he is in the dark over an appointment but would be willing to help if the new man needed to tap into his experience.
He told BBC Sport: “I shared a dressing room with Ryan and he is a great fellow, a top fellow – I think the players would play for him.
“It’s hard to call whoever gets it, but being a Welshman myself they will have my support whoever gets it. But I couldn’t tell you who is going to get it as I don’t know.
“With my six years in that job I know my way around the international track, but if anybody wants to talk to me about my experience they can 100%.”
