The Fiji Airways Flying Fijians arrive into the country today and will head into preparation mode for the match against Canada.
Coach John McKee says they made some critical mistakes in defence in their game against Japan.
He says there were little system errors where players either did not understand their role probably or did not execute their role as they should have.
McKee says once they were behind and chasing the game, they lacked composure to build the pressure and also tried to force the play too much which resulted in turnovers.
Fiji will face Canada at 5.15pm in the Pacific Nations Cup this Saturday at the ANZ Stadium.
