Hit him hard and hit him early.

That is the simple game plan Melbourne's forwards will take into Sunday's NRL grand final to stop Parramatta's runaway freight train Fuifui Moimoi.

The giant Kiwi Test forward has been one of Parramatta's stars in their Cinderella run to the decider with his rampaging forward thrusts and heavy defence setting a platform for Jarryd Hayne to run his magic.

Moimoi isn't the most aerobic player in the competition and Melbourne's forwards believe they've identified the best way to limit his inspiring runs.

"You don't like to see Fui with a lot of steam up so you have to try to get up in his face and knock him over before he hits top speed," said Storm lock Dallas Johnson.

"It's a big challenge so we have to get plenty of numbers into him to knock him over.

"With a full head of steam, he's a big boy and he runs really hard so I'm sure we'll get plenty of boys into him."

Storm prop Jeff Lima, a good friend of Moimoi's, said the Parramatta prop had set a new standard of performance for NRL front-rowers with his efforts in 2009.

"He's certainly playing good footy these last couple of weeks and he's been good for the team," said Lima.

"He's the benchmark front-rower for the NRL this year so you've got to get out there and do your best to stop him.

"He's had it in him, he just had to find the extra spark on the football field.

"Certainly he's been working hard with a trainer, I've heard instead of doing six minutes he's doing 20. He's fit and he's getting better and better every week."

Storm second-rower Adam Blair has played in two losing grand finals and he says it will be up to the middle men to put Melbourne on the right path towards victory.

"I think it all starts in the middle. If you stop the forwards going forward you will limit the opportunity that the backs get," said Blair.

"I think it all starts from the front, we have to come out and meet them.

"Our forwards have been outstanding and the challenge is going to be set for us and we just have to meet them ... don't wait for them to make the moves and you're in with every chance of winning the game.

"You can't sit back and let them come at you ... we have to come out firing right from the start."
