The S-League suffered its second managerial casualty in two months when Philippe Aw was relieved of first-team coaching duties at Home United yesterday.
He will be replaced by former assistant Aidil Sharin, 38, from today. Aw, 39, will be redeployed as the club's head of youth development and performance management.
Jorg Steinebrunner was the first head coach to go when he left Warriors FC in May.
Home are fourth in the S-League after 16 matches, 16 points behind leaders Albirex Niigata.
Aw declined to comment, but The Sunday Times understands he has not taken up his new appointment officially and is considering his options.
The club did not explain the reshuffle. A statement on the club's Facebook page only said the coach's experience in youth football - Aw was the formerly the club's Prime League coach - means the Protectors' youth set-up is in good hands.
The post also said Aw had performed "admirably" over the past two seasons and credited him for grooming several youngsters.
In his new role, Aw, a former wing-back with Home, will head the Centre of Excellence, kids academy and scouting programmes.
A father of three, Aw, who won one S-League title and two Singapore Cups as a player, was appointed head coach when South Korean Lee Lim Saeng resigned at the end of the 2014 campaign.
He promoted many of the club's Prime League players and handed first-team debuts to several youngsters, including Shahrin Saberin, 21, and Syahiran Miswan, 22.
A firm believer in playing an attractive and attacking game, he won plaudits for his style, even if it did not always bear fruit.
In his first season, Home finished sixth in the 10-team S-League. He also guided the Protectors to the Singapore Cup final, where they lost 1-2 to Albirex.
The Protectors' next match is a league home match against the Warriors on Thursday.
