The FFA has recruited former Socceroos Paul Okon, Craig Moore and Vince Grella to help Australian Institute of Sport coach Tony Vidmar and technical director Peter de Roo to pick rising stars at the national institute challenge in Canberra.

The tournament for the best under-15s players will finish on Saturday with an all-stars team to play against the highest ranked institute after a week of intense matches. The top-performing players will be rewarded with AIS scholarships and a spot in Australia's under-17s team leading into the 2015 World Cup in Chile.

Okon, Moore and Grella, all former Socceroos captains, have taken on player mentor roles.

''The pool is getting bigger and the choices are getting harder,'' de Roo said.

''Have we seen the next Harry Kewell yet? Maybe not. But there are more players to choose from and the standard of football is getting better.''

Teams representing the ACT Academy of Sport, NSW, Queensland, South Australia, Northern Territory, Tasmania, Football West, Victoria and the Emerging Jets played eight games over the past five days.

ACTAS finished the tournament on a high, thrashing the Northern Territory 5-0, with Sam Smith scoring a double.

The Canberra team finished the tournaments with two wins, four draws and two losses.

Vidmar, who played 76 games for the Socceroos, was impressed with the standard of play.

''There's definitely a pathway for kids to stay in Australia and the best players will come to the AIS. The players who miss out will go to the A-League,'' he said.

''There has to be that grounding and this is a great environment.''
