Port Adelaide coach Ken Hinkley has revealed a clause in his contract that requires his side to make finals for him to continue to be the head coach of the Power beyond 2020.

Footy Classified's Caroline Wilson reported on Monday night's episode that Hinkley must make finals in one of his first three years of his contract to garner an extension in 2021.

Hinkley signed a three-year deal to continue his role as Power coach in September 2017.

The Power were unable to make finals last year and their season comes down to the wire this weekend in a game against Fremantle.

Should the Power win, they must rely on other results to see them into the top eight.

“I’m quite happy to say that my contract has clauses in it, everyone’s contract has some type of clause in it. If you don’t perform you don’t deserve to get those add-ons of a contract,” Hinkley told SEN SA breakfast.

“I’m quite happy to say that if we don’t make finals, I won’t be the coach of the football club in the near future but that’s what it should be, that’s what we set out to be."

For the Power to make finals, West Coast must defeat Hawthorn in Perth this Saturday night.

They then need to rely on Adelaide to defeat the Bulldogs in Ballarat on Sunday afternoon, and then they themselves have to beat the Dockers by a greater margin than that of the Crows.

If all goes to plan, Port Adelaide will finish eighth on 44 points gaining entry to the finals via percentage.
