The Singapore national Under-15 and Under-18 sides will need new men to lead them after respective coaches Nazri Nasir and Dejan Gluscevic were told their contracts would not be renewed.
Both men's contracts will expire in the upcoming months and, together with U13 coach Nor Azli, are set to part ways with the Football Association of Singapore.
This came after an annual review by the FAS and the decision was explained in a statement to Goal Singapore by an FAS spokesperson when contacted.
"Following the annual review, coupled with our strategic direction and future plans for youth football, FAS has decided that we would not renew the contracts of our staff coaches Nazri Nasir, Dejan Glusevic and Nor Azli when their contracts expire in the coming months," it read.
"In accordance with their respective contractual clauses, we had earlier explained to them our decision. Developing coaches is a key priority for us and we will continue to invite them to our coaching seminars and conferences.
"We would like to express our appreciation to our coaches for their contributions to Singapore football and we wish them all the best."
Former Singapore captain Nazri brought the U15 side to second place in both the U16 Centre of Excellence (COE) league and Challenge Cup last year, and followed it up with the U18 COE title this year. The 42-year-old also guided them at the Lion City Cup in both 2012 and 2013, although they failed to win any games in both editions.
Serbian Gluscevic helped to develop current starlets Adam Swandi and Mahathir Azeman, both of whom now ply their trade overseas with FC Metz (France) and Boavista SC (Brazil) respectively. He also led the U16s at the 2011 and 2012 Lion City Cups, where they lost in the final in the latter tournament.
The former Tanjong Pagar United player, who was first appointed as head coach of the U14 side back in 2010, also led the U18s to the runners-up spot in this year's Prime League. Gluscevic was also in charge of the U18s when they crashed out at the group stages of the recent AFF U19 Championship.
