The Samoan side are second in the Champions League Qualifier standings, with one win and one loss from the opening two rounds in Pago Pago.
A draw against Tonga's Veitongo FC would be enough to join Tupapa Maraerenga in reaching the main draw but coach Paul Ualesi says they won't be holding back.
"The boys are preparing really well for Veitongo, our brothers from Tonga because we respect them as well," he said.
