PORT Adelaide key forward Charlie Dixon is ready to lead from the front in his long-awaited finals debut, winger Jared Polec says.

After 105 games, seven seasons and a change of clubs, Dixon will play a vital role for the Power in Saturday night's elimination final with West Coast at Adelaide Oval.

The 26-year-old has had a magnificent season, kicking a career-high 46 goals (10th in the League) and leading the competition in contested marks.

Dixon also has career-high numbers in tackles (3.0 per game), inside 50s (3.4 per game) and possessions (14.2), while importantly playing all 22 games for the first time in his injury-interrupted career.

"He's a good leader and owns the forward line," Polec told AFL.com.au.

"He demands a lot from the younger boys playing up forward and sets the tone.

"Knowing we've got a target down there that can take a mark or bring it to ground is good to have.

"It's a get-out-of-jail card for us, which is a very important thing."

Dixon played 65 games in five seasons with Gold Coast before joining the Power on a lucrative five-year deal at the end of 2015.

He's running into form at the right time of the year, booting eight goals in his past two games against the Western Bulldogs and the Suns in rounds 22 and 23.

Dixon has also kicked eight goals in his two games with the Eagles this year, including a match-winning five-goal haul in the Power's round 16 win at Domain Stadium.

The Power must get the ball to Dixon quickly to prevent the Eagles dropping defenders back and taking intercept marks, as was the case in West Coast’s round-seven victory at Adelaide Oval.

Despite having 68 inside 50s to 39, the Power lost the game by 10 points.

"The conversion rate wasn't good enough and we were giving them chances to drop off and take marks," Polec said.

"All season we've been practising our inside 50 conversions and hopefully it won't happen again this week."

The Power won their last three games of the season in response to an embarrassing 84-point loss to cross-town rivals Adelaide.

"Our ball movement wasn't up to scratch and our contested ball wasn't anywhere up to scratch," Polec said.

"It opened our eyes to the way we were playing and the way we needed to play.

"So it was probably the loss we needed to have."
