FRUSTRATED Port Adelaide chairman David Koch says coach Ken Hinkley and his football department will face a searching review at the end of the AFL season.

Koch admits missing the finals would be another failed season but insists the end-of-year review won't necessarily carry added heat for Hinkley.

"Ken is sort of the butt of all the criticism," Koch told 5AA radio on Monday.

"And he understands that. He is the person that has to deliver the performances and get the team up to perform at their best ... he accepts that fully."

The Power have slipped to 10th spot on the ladder, a win behind eighth-placed Adelaide.

Hinkley is contracted until the end of the 2021 season but Port could miss the finals for a fourth time in the past five years.

"We reviewed the entire club at the end of last year and will be doing it again at the end of this year," he said.

"We are still one game (win) out of the finals, as weird as that seems at the moment.

Our members are disappointed with the lack of consistency in our team, as we all are - David Koch

"... Ken also said last week, I have been saying it for a couple of years, that our pass or fail mark that we set ourselves is making the finals.

"And that is important for us all. Our members expect it, we expect it."

Koch acknowledged some unrest among the club's fan base at the prospect of failing short of finals.

"Our members are disappointed with the lack of consistency in our team, as we all are," he said.

"And they are expressing that - and they have every right to express that.

"They want more consistency in terms of the team and we all do."

The Power president said everyone within the club was trying to mend the trend of inconsistent performances.

"We are absolutely aware of that and if people think we're not trying to do something about it, they have got rocks in their head," he said.

"We have great belief in the coaching department and the football squad at the moment.

"The young talent that is there and have been blooded is extraordinary, the number of under 23-year-olds is huge ... but we have got to deliver results now, not promise the future."
