VETERAN Fremantle midfielder David Mundy is set to go again in 2020 with the 34-year-old signing a one-year contract extension. 

The durable Mundy played all 22 games this season which is the second consecutive year he hasn't missed a home and away game.

He now sits on 316 career games and believes he can still deliver at AFL level.

"I've been thinking about (re-signing) fairly seriously throughout the entire year - gauging my mental desire, physical abilities and how much I was still contributing to the team," Mundy said. 

"In my discussions with my management and family, we agreed we're always keen to go on as long as I'm valuable on field."

Following the retirements of Hayden Ballantyne and Aaron Sandilands, Mundy is currently the only Freo Docker on the list older than 30 years of age.

He said he was looking forward to continuing his work with the emerging playing group.

"I think we've got a really great core of young guys coming through who are really dedicated to their craft and want to get as good as they can really quickly, which is great," Mundy said.

"Obviously (the departures of) Aaron Sandilands and Hayden Ballantyne leave a huge void in terms of leadership and also performance, so that is going to be a challenge for the next generation. 

"I think we're on a really great growth curve. We saw some really good improvement this year and I think we're on the right track.

"We'll obviously get (a new senior coach) into the club, which will refresh things and provide us with a slightly new direction.
"With the core group of players that we've got, we'll go OK."
