PNG lost their last match against Laos 3-1 at the Gelora Bung Karno Stadium in Jakarta on Sunday night.
Midfielder Ronald Conn scored the only goal in the second-half from a cross courtesy of substitute Jamal Seeto.
Laos scored two soft goals in the first half and despite PNG fighting back and pulling one back through Conn, the latter held on to win.
Indonesia eventually won the tournament and receive USD$50,000 for their efforts. Laos finished second, the Maldives third and PNG fourth collecting USD$10,000.
Wangu, who played in the last South Pacific Games gold winning team in 1987 in Noumea, New Caledonia said the team performed to expectations against three quality nation’s from the Asia Football Confederation (AFC).
PNG also lost to the Maldives 1-0 and hosts Indonesia 6-0.
Wangu, a resident working in Jakarta who witnessed the two matches against Indonesia and Laos said he was proud of the team because they never gave up and continued to attack despite facing better structured teams.
“The boys were competitive and showed glimpses of their fighting spirit which Papua New Guineans always show, but to be realistic we don’t play enough at this level to know how to handle these teams,” he added.
“It’s not easy to play at this level especially against this very good Indonesian team which is well financed and have been together for the past five years,” he said.
“Losing 6-0 is not bad when you consider they beat the South Korean senior team and are deemed to be better than their senior team,” he said.
“This team is also preparing for the South East Games and are the pride and joy of the Indonesian soccer mad people,” he added.
Wangu said with the prospect of these players likely to feature in the 2015 Pacific Games, the former Guria Port Moresby player further challenged the players to repeat their 1987 performance.
