CLUB stalwart Craig Deans and youth-team coach Daniel McBreen have parted company with the Newcastle Jets amid suggestions they have lost faith in the club's management.
McBreen was told last week his contract, which was due to expire at the end of June, would not be renewed.
It was mutually agreed he would coach Newcastle's under-20s in one more game - their 5-2 win against Hawkesbury City on Saturday - before standing down.
First-team assistant coach and analyst Riccardo Marchioli will replace McBreen until at least the end of the season.
It is understood McBreen will remain involved in football as a commentator for Channel 10.
Within days of the departure of McBreen, who played professional for 15 years in both the A-League and abroad, Deans handed in his resignation.
The 47-year-old has been a mainstay at the Jets since the club's foundation season, firstly as a player, then as a youth-team and W-League coach and in three stints as A-League head coach - twice in a caretaker capacity before a full-time stint last season.
This season he has been acting as the club's football-operations manager.
It is understood the futures of Newcastle's under-18 coach, Peter McGuinness, and Academy director Kew Jaliens are also uncertain.
The Newcastle Herald contacted Deans and McBreen over the weekend but neither was willing to comment.
Jets CEO Shane Mattiske said staff turnover was part and parcel of football but wished both of former employees well.
"Craig is someone who has made a great contribution to the club over a large number of years," Mattiske said.
"He's always someone who will be looked on as part of our family. But we respect his right to make decisions and wish him well.
"In relation to Daniel, he's developed strongly and is emerging as a good coach, and he's also become a great media talent and I'm sure he'll continue to make a great contribution across the A-League landscape."
