Moses Toata and Co. started the match on the front foot as Solomon Islands international Gagame Feni open the scoring in 10 minutes of play.

Toata told Sunday Sports the win is very important for his team.
“Opening games are always hard but the boys manage to come clean with a 4-0 win today (yesterday),” he said.
“Although the combination was not really what I expected, the win is very important to us,” Toata added.
The win puts Warriors in the driving seat since they are determined to back on the top this season.
