The second-placed Mariners host the Roar in the first leg of their two-legged final at Bluetongue Stadium on Saturday night and Rose, who was been one of the best defenders in the competition this season, feels Graham Arnoldâ€™s men are good enough to get the result they are after.
"There's definitely confidence in our dressing room that we can beat them," Rose said.
"They play a great style of football, they have done all year and I think we've improved as the season's gone on.
"I think we have the same, if not very close, sort of style of play and standard that they're setting at the moment.
"I think we're right there or thereabouts anyway."
And Rose was full of praise for the job his new club has done after returning to Australia following four years in Romania.
"I've really enjoyed my football this year," he added.
"Central Coast is a great place, the boys have been great since day one.
"Arnie's sort of given me the chance to express myself on the pitch and I think that helps a lot.
"To come back and play this well in my first year, it's more than I dreamed of and I've enjoyed every minute of it."
