Cook Islands champions Puaikura thrashed Veitongo FC from Tonga 4-0 on Saturday while Lupe edged American Samoa's Utelei Youth 4-3 in their opening encounter.
Puaikura coach Matt Calcott said his side was a bit rusty first up but should be better for the game.
"We're hoping to see an improvement in combinations, possession and probably a little bit more pressure. Our pressure lines need to be improved and we'll make sure they are given the work we've done in training this morning," he told OFC.
He said the whole squad knows how much is riding on today's game.
