Melbourne halfback Cooper Cronk says the Storm are ready to peak for next weekend's NRL grand final against Parramatta.

The Storm secured a spot in their fourth straight grand final with a 40-10 mauling of Brisbane on Saturday night and have already been posted as outright favourites against the Eels.

Cronk says the Storm are confident with their own form having also beaten reigning premiers Manly 40-12 on their way to the decider.

"It's obviously a good time of year to be playing footy," said Cronk at Melbourne's recovery session on Sunday.

"It was a good performance and you go into finals always wanting to play your best footy.

"Over the last month or five weeks we've been really concentrating on the way we've been going about our business."

While the Eels will have a drama-filled build-up with possible suspensions and an injury to skipper Nathan Cayless (hamstring) likely to distract their preparations, the Storm have only clear skies ahead.

Prop Brett White has a slight shoulder problem, replacement hooker Ryan Hinchcliffe has a knee concern and Brett Finch a corked calf but all are expected to be cleared to play.

"I'm pretty sure everyone is fit and healthy," said Cronk.

"I don't think anyone is going to miss this game. Most blokes would bend over backwards to have a crack at it."
