Fulham manager Kit Symons is stepping down from his role as Wales assistant manager to focus on Fulham.
The 44-year-old has been working alongside Chris Coleman since his appointment as Dragons manager in 2012.
However, Symons became a No 1 himself in October last year when he was promoted from his U21s role with the Whites to first-team boss after taking over from Felix Magath.
Becoming Craven Cottage chief has made combining two roles increasingly difficult for Symons and last week's memorable 1-0 win over Belgium was his final involvement with the national team.
"We will have a chat but I think Kit will have to stop and concentrate on Fulham," Coleman said.
"It will be a shame for him to go as he has done really well, but managing a club and working with your country is very difficult to do.
"He is probably very emotional as he has represented Wales for 25 years as a player and coach and I will miss him.
"I have got his replacement, but he is in work at a club and until he puts pen to paper we cannot make it official."
Symons is looking to improve on last season's 17th place finish in the Championship and will be hoping the time recouped from his decision to step down will pay dividends for Fulham next term.
Fulham, who were relegated from the Premier League in the 2013-14 season, had picked up just one point from their first seven league matches of the last campaign when Symons replaced Magath as manager, initially on an interim basis.
In October, he was given a deal until the summer of 2016 after the club took 13 points from a possible 21.
The Craven Cottage side eventually finished 17th in the table, 11 points above the relegation zone.
