Speaking at his weekly media conference on Thursday, the Collingwood coach shared his admiration for North Melbourne and its brand.
"I think they're a terrific side. I look at that side and think, they're young and aggressive, with a fantastic game structure," Malthouse said.
"I admire the coach (Brad Scott) and I admire their club spirit - we're in for a fight."
North Melbourne has lost five games by under three goals this season, but Malthouse believes it's only a matter of time before things turn around.
"The win-loss ratio - I think they've been very, very stiff in a couple of decisions that may well have gone either way for them.
"I've had them in the eight before the season started and I still think they've got a wonderful chance to be in the eight."
