Joe Roach is leaving Bournemouth.
The 62 year-old, who joined back in 2001, has served various roles within the coaching staff team, including as caretaker manager.
Roach told the club's website: “No football club can exist without committed, passionate supporters and this football club has had the privilege to receive the backing of them in good times and bad.
“Thank you to those of you who have historically supported the club and those who helped keep the academy alive in its early stages of development."
