HITC Sport understands former Charlton star set to leave first-team coaching role.
Jason Euell is set to return to his role as Under-21s coach at Charlton after failing to agree a deal to stay on as a first-team coach, HITC Sport understands from sources close to the club.
The 39-year-old stepped up to coaching the Charlton first-team on a temporary basis following the sacking of Guy Luzon last October.
Euell stayed on in the role when Jose Riga returned to the Valley as manager last month and the former Jamaica international had impressed during his time working with the first-team.
Charlton were hoping to keep Euell on the first-team coaching staff, but they have been unable to agree a deal with the Addicks legend.
A source close to the club has told HITC Sport that the interim first-team coach is very disappointed that he was unable to agree basic terms with the club.
The source also added Euell was unhappy about the length of time the process of offering him a deal to stay as first-team coach took.
Euell, who grew up in south london was a club record signing in July 2001 and joined the club again in 2011 and the club is close to his heart as he has seen the club's progression and regression.
Euell is expected to returning to his role as under 21's manager where he has played a key part and had success in bringing young players through the ranks such as Diego Poyet, Harry Lennon, Morgan Fox, Karlan Ahearne-Grant, Ademola Lookman and Regan Charles-Cook to name a few.
