Cook Islands goal keeper (GK), Anania Piri said good planning had led to the team’s success so far.
“We basically go into our own cell groups and plan out our goals for each of those groups and that’s what we try to achieve as a team and also as individuals,” Piri said in a post-match interview.
“We have the motivation for everything when we strive to play for our families, play for each other and play for ourselves.
“I want my family back home to watch and make my parents proud.”
The win against Swaziland sees the Cook Islands, which is unranked, maintaining its lead on the points table, followed by Ireland.
