Matawalu said they won the shield for the first time last year after beating Army 39-24 and are aiming to make it two in a row.
Matawalu added when Navy plays, it is not only a game to them but a war which they have to win.
Flying Fijians Maikeli Mocetadra, Benedito Koroi, former sevens reps Josaia Lotawa , Sikeli Vuruna along with former flying Fijians Manasa Saulo and Vesi Rarawa will bolster the Navy side tomorrow.
Navy will meet Raiwaqa at 1pm in the first semifinal for Fiji’s oldest trophy while Police will meet Army in what is dubbed as the pre-Sukuna Bowl match in another semifinal.
