Emerging midfielder Trent Dumont wants to spend his entire career at North Melbourne after signing a new two-year deal with the Roos.

Dumont played 20 senior games in his first three seasons at Arden St despite strong VFL form, with Andrew Swallow, Jack Ziebell and Ben Cunnington firmly entrenched as the Kangaroos' starting inside midfielders.

The 21-year-old South Australian told AFL.com.au he had never seriously considered seeking greater opportunities at other clubs when his contract expired at the end of this season, totally dismissing recent speculation linking him to a move to Adelaide. 

"You do wonder sometimes whether you'll ever (cement a senior spot), but I just focused on working on my own game and I guess you back yourself to be able to find a regular spot eventually," Dumont said.

"If you just keep playing good footy, they'll reward it and I think that's happening this year."

Dumont has become a key member of North's midfield in 2017.

Over the first six rounds, he has averaged 21.5 possessions (fifth at North), 10 contested possessions (third), 4.2 clearances (third) and 3.8 tackles (equal sixth) a game. He has also led North in total inside 50s (27) and is equal second for goal assists (5).

Dumont has done this while playing regular run-with roles, having spent time on Patrick Dangerfield, Marcus Bontempelli and Nat Fyfe.

Dumont says he is expected to maintain an attacking focus when playing on such stars while keeping them accountable at stoppages.

Playing these roles has also given Dumont a chance to learn from the game's best, something he has relished.

"They have moments when they beat you and we review that and look at it, and that's what makes them great," Dumont said.

"I did a bit of a role on Sam Mitchell last year as well and the way he moves and cuts I've tried to take a bit out of that as well.

"I just try to look at their strengths as much as possible. Obviously, I try to nullify them on the weekend, but I then try to bring their strengths into my game if I can."

Dumont has appreciated the faith North has shown in assigning him key run-with roles.

The Roos have also restructured their midfield this year to give youngsters like Dumont more time in the centre square, most notably moving former skipper Andrew Swallow into a high half-forward role and, as of last round, a stint in the VFL.

Dumont, however, downplays suggestions there's been a changing of the midfield guard at Arden St in 2017.

"It's just a bit more flexibility through there. A lot of people's efforts have been rewarded, everyone's just got to be on their toes to be selected each week," he said.

Asked what he hopes to achieve from the rest of the season, Dumont is keeping things simple.

"I'm just looking to be bolder with my movement, breaking through the front of stoppages," he said.

"I'll always keep working on my fitness and strength. My strengths are my clean hands and decision-making, so I'll try to really keep them up to scratch as well."

Dumont is enjoying being able to maintain such a simple focus after robbery charges against him from an October 2014 incident were finally dropped this January.

Significantly, that two-year ordeal reinforced to Dumont that North Melbourne was his football home.

"I was really, really happy with how the club supported me. It felt like a second family almost and I was willing just try everything I had to stay here," he said.

"I would love to just stay here for my whole career.

"Obviously, I've got my family back in South Australia and it would be nice to be around them, but I love North Melbourne so I was pretty keen to stay here and get a done as soon as possible.

"It's an awesome feeling."
