SOME people look at Adelaide key forward Kurt Tippett and wonder whether his mind is totally on the Crows' finals campaign.

But new Carlton coach Mick Malthouse still sees a big headache for the Hawthorn defence in next Saturday's preliminary final.

Tippett only kicked one goal in Friday night's semi-final win over Fremantle and team-mate Taylor Walker gifted that to him.

There is speculation Tippett will leave Adelaide at the end of this season and go to either Gold Coast or Brisbane. Players from both Queensland clubs have expressed their desire to land the out-of-contract Crows forward.

But as Crows fans fret over whether the key forward is thinking more about his next club than his current one, Malthouse says Tippett remains a big factor regardless of his form.

"He's certainly not playing with the same intensity, but it's so important for Adelaide to have the two players standing 30 (metres) apart to break up what Hawthorn do as well as anyone, and that's get the third man across," Malthouse said on Channel Seven's Game Day.

"Whether he's playing well or not, he's still a dangerous player - you kick the football on his head and he's able to mark it, he'll have shots for goal.

"It's funny with big blokes, particularly if you're a forward, you're in and out of form.

"But you're in and out of form because of what's happening in front of you and you're in and out of form ... because if you're doing well, a third man will inevitably come over the top of you."

Hawks defender Josh Gibson noted that Collingwood key forward Travis Cloke's form was also under scrutiny ahead of the finals, before he kicked five goals and then another six in successive games.

"Key forwards don't stay down for long and he's a ripper mark," Gibson said of Tippett.

Hawthorn will also put a lot of time this week into working out a plan for Crows forward Taylor Walker, who broke the game apart against Fremantle on Friday night with five goals.

"He was probably the firestarter the other night, his presence on the field - he took marks, kicked goals, got the crowd involved," Gibson said.

The Hawks will start strong favourites for Saturday's twilight preliminary final against Adelaide at the MCG, but Crows midfielder Rory Sloane said they will back themselves.

"We definitely do have that belief, especially after the weekend," Sloane said.

"Winning our first final might help settle the nerves now.

"Playing at the MCG, playing in front of a big crowd, a preliminary final - anything can happen.

"We're definitely in some good form and as a team we definitely have the belief we can match it with them."
