"But there's plenty of room for an upset to happen so drawing hard and fast conclusions about the outcome of this group is hasty," he says.
While Group A features three closely matched sides, Group B throws forward a stern challenge for the two Oceania representatives.
Last season's OFC Champions League runners-up Amicale and FIFA U-20 World Cup-bound Fiji take on former Bahraini premier league champions Busaiteen.
The fulltime professional Bahrainis have plenty of pedigree but they are struggling in their 10-team domestic competition languishing in eighth after four rounds.
"Busaiteen, despite their domestic struggles, will be favourites to top Group B but you can't write off Amicale who surprised everybody with their run to the OFC Champions League final last season.
"Fiji U-20 may have their work cut out to qualify for the final but Ravinesh Kumar will just be happy to see his youngsters get some tough preparatory matches under their belt in New Zealand conditions," Song says.
Amicale are in a rebuilding phase after surrendering their domestic title to arch-rivals Tafea FC and finishing third at the inaugural Melanesian Super Cup in Port Vila last week.
Fiji U-20 are cast as the competition's underdogs with Ravinesh Kumar and technical advisor Frank Farina eyeing next year's FIFA U-20 World Cup in New Zealand as their priority.
The tournament will be held at The Trusts Arena in Auckland, New Zealand, from November 17-23.
The teams have been split into two groups and will compete in a round robin system before advancing to a play-off to determine the final placings on November 23.
The groups are as follows:
Group A
Auckland City FC (New Zealand)
Singapore U-23 (Asian Football Confederation)
Bodden Town (Cayman Islands)
Group B
Amicale (Vanuatu)
Busaiteen (Bahrain)
Fiji U-20 (Oceania Football Confederation)
