The Swire Shipping Fiji Warriors side knows it will be a crucial match when it battles its Pacific rival Tonga A in the opening match

The World Rugby Pacific Challenge kicks off on Friday.

The Senirusi Seruvakula-coached side hammered Tonga 57 -7 in the final round of the WRPC last year.

Seruvakula says there is a lot of work- on needed in camp so that they can counter the physical Tongan defense.

“This morning when we have our team meeting there’s a room for improvement as you all know we just came back together last week and there’s lot of work on and that’ was we doing this morning.”

The Fiji Warriors will take on Tonga at 5pm on Friday at the ANZ Stadium.

Meanwhile, Junior Japan meets Samoa earlier at 2.30pm on Friday at the same venue.
