North Melbourne coach David Noble says the club needs to "stick together" after suffering a fourth consecutive heavy defeat, losing by 78 points to Fremantle on Friday night.

The Kangaroos have lost by a cumulative 256 points over the past four games, conceding more than 100 points in five of the past six games, leaving them second-last with a 1-7 record. North's only victory this season came in round two against a depleted West Coast.

Friday's score of 3.6 (24) was their ninth equal lowest in club history, having lost the inside-50 count 67-32.

"We've got to stick together," Noble said. "We've got find the positives out of it.

"At the end of the day it's about how much we learn from this period.

"It's not about the fails, the failure of where we're at, it's about what we learn.

"It's about how we address that going forward to keep the players bubbling along."

Noble bemoaned his side's turnovers against the Dockers, who have won plaudits for their pressure this season.

"Stop turning the ball over," he said. "They're hard to penetrate but when you give the ball back you get punished severely.

"We've got other parts of our game but I thought that was the major part tonight."

He added: "We've been doing a lot of work behind the scenes in our contested footy. We didn’t fare too well in clearances tonight. It feels like each week we've got one thing that pops up where we get severely taken advantage of."

Noble said the knee injury that forced Ben McKay to be subbed out appeared to be a medial issue, while he pointed to Will Phillips and Tom Powell as options to apply pressure for selection via the VFL.
