PORT Adelaide coach Ken Hinkley has no doubt he'll remain in the top job next year as the Power strives to make amends for a failed season.

With finals already out of the equation, the Power rounded out their up-and-down campaign with a 43-point thumping of Fremantle at Adelaide Oval on Sunday.

Hinkley's position had come under external pressure after it was revealed he had a clause for the final year of his contract in 2021.

However, he said he was extremely confident the club would allow him to remain in the role next year.

"I'm really optimistic about working with the group for the continuation of the journey, there's no problems with that at all," Hinkley said.

"I was always confident that as a footy club we were going to follow through. 

MISSED THE FINALS? Your club's first off-season priority

"The hard part about the game is the outside stuff that starts to build and it gets a bit of momentum, so that creates some uncertainty. 

"I've got their (the board's) support, I've got nothing to worry about as far as that goes, but from the reporting that goes on, you do get some self-doubt.

"When you get players and key personnel at your football club supporting you and wrapping their arms around you and engaging in what they want and what they need, you just know you're on the right path and you're the right person to help on that path."

The Power have finished 10th on the ladder for a second straight season, despite having an 11-11 record this year compared to a 12-10 mark in 2018.

It's the fourth time in the past five years they have missed the finals, but comes after a dramatic rebuild at the end of last season when several experienced players left the club.

Chad Wingard, Jared Polec, Jasper Pittard and Jack Hombsch found new homes, with the Power bringing in first-round draft picks Connor Rozee, Xavier Duursma and Zak Butters.

They also added West Coast ruckman Scott Lycett on a five-year deal and former Hawthorn defender Ryan Burton.

"At the start of the year we set out to play finals and we failed to do that," he said.

"That does leave you a little bit hollow (after a big round 23 win).

"We might be one less win (than last year), but there feels like there's a fair bit of difference.

"One that creates a lot of optimism and enthusiasm in me and in the group, I reckon, to keep striving and continue to get better again. 

"It's slightly hollow because we didn't get where we wanted to go this year."
