PORT Adelaide midfielder Ollie Wines is among a select handful of Power players who will embark on a pre-season training camp in the United States.

Wines is keen to build up his fitness base for next season as the Power aims to return to the finals in 2017. 

The 21-year-old is averaging a career-high 25.9 possessions per game, but knows he can take his game to another level.

"We're going to head over to the States, a little group of the boys, we're going on a bit of a training camp with (the Power's head of high performance) Darren Burgess," Wines told Seven News on Tuesday night.

"I only tend to play 70 per cent (game time), which is relatively low for a midfielder, so when I am out there, I know I have to work really hard and get to as many contests as I can. 

"As a playing group, we know our skills aren't up to scratch.

"At times when we do get the ball we make poor decisions and turn the ball over too easily."

Wines said he had full faith in Power coach Ken Hinkley, the rest of the club's coaching staff and playing list after reports surfaced of a shake-up in the off-season.

The Power go in as massive underdogs for Saturday night's Showdown with cross-town rivals Adelaide at Adelaide Oval.

The third-placed Crows have won 11 of their past 12 games to have serious premiership aspirations, while the Power are coming off big losses to the Sydney Swans and Melbourne.

"Obviously there's a lot riding on these games, there are bragging rights twice a year that we get the opportunity to play for," Wines said.

"We want to prove something to ourselves that we can play at that level."
