"They're obviously important players for us but Ngani and Suaia did a terrific job coming in as replacements and Glen was outstanding, picking up the players' player of the day award.
"We'll see how we progress through the rest of the week.''
Both coaching staff and players valued Sunday's hard-earned 18-16 win over fourth-placed Manly as the club's most important so far, with Elliott describing it as the most meaningful because it was achieved against a quality side. But this weekend's looms as just as important given the Warriors have a bye the following week and want to continue the momentum they have established since their humiliating 62-6 defeat to Penrith three weeks ago.
The third-placed Roosters beat the Warriors 16-14 when the two sides met in the second round at Eden Park and since then have gone on to fashion a record of nine wins and three defeats.
Warriors side to play the Roosters at Allianz Stadium, Sydney, on Sunday (8.30pm NZT): Kevin Locke, Glen Fisiiahi, Dane Nielsen, Konrad Hurrell, Manu Vatuvei, Thomas Leuluai, Shaun Johnson, Sam Rapira, Nathan Friend, Russell Packer, Feleti Mateo, Simon Mannering (c), Elijah Taylor. Interchange: Ben Matulino, Jacob Lillyman, Sebastine Ikahihifo, Dominique Peyroux, Ngani Laumape, Suaia Matagi, Charlie Gubb (three to be omitted).
