An undermanned North Melbourne won't fall for the trap of focusing solely on stopping Fremantle superstar Nat Fyfe on Saturday night, with Roos coach Brad Scott saying the Freo Dockers boast other midfield stars who demand respect.

North will take on Freo at Domain Stadium without three of its best midfielders: captain Andrew Swallow (thumb), Daniel Wells (Achilles tendon) and Nick Dal Santo (hamstring).

But Scott told reporters on Wednesday that North was confident it had the depth to cover those key losses, pointing out that the Roos had beaten Fremantle in Perth in round six last year without Swallow, Wells and 2013 best and fairest winner Scott Thompson.

Scott freely admitted the ladder-leading Fremantle Dockers presented "a significant challenge" but said the Roos couldn't afford to get caught up in the "mystique" of Fyfe, despite his blistering start to 2015 that many people think has lifted him above Gary Ablett as the AFL's best player.

"We've some pretty good midfielders as well who are in good form, so we'll just take him on," Scott said of Fyfe.

"Clearly we've got a lot of respect for him as everyone does, but sometimes the mystique can build to a point where people think he's unstoppable.

"He's a really good player but every team's got really good players."

Scott said North's match committee had yet to decide whether to run a hard tag on Fyfe.

"I've said before with other teams that have got really good individuals, that if you focus purely on them you take your eye off (David) Mundy, and I think that's disrespectful to Mundy," he said.

"I think it's disrespectful to Stephen Hill and Michael Barlow and Lachie Neale and Danyle Pearce.

"They've got a really solid midfield, a solid list and a solid team."
