PORT Adelaide defender Jasper Pittard expects the Brisbane Lions to draw on last year's upset victory as proof they can do it again.

The 10th-placed Power must win their remaining five games to remain a slim chance of sneaking into the finals, starting with Saturday night's encounter with the Lions at the Gabba.

The Power suffered a shock 37-point loss to the Lions in Brisbane last year, a defeat which came back to haunt them later in the season.

"I look at that game as one of the worst losses we've had,'' Pittard said.

''We went over there expecting to win, coming off two good years and they played a lot better than us on the day.

''It was really disappointing and in hindsight could have cost the season last year.

''They rocked up on the day and played better and I'm sure they will use that as motivation this week.

''They had a good win last week and they'll be thinking 'we got them here last year' so that makes it a bit more interesting for us going into the game.

''It will be a challenge for sure.''

The Lions enjoyed their second win of the season when they defeated Essendon at Etihad Stadium last weekend.

The Power held a handy lead over Greater Western Sydney at half-time before being overrun by the Giants in the second half at Adelaide Oval last Sunday.

"Obviously disappointed after the weekend, but felt like we played some pretty good footy against a very good side,'' Pittard said.

''You can't really change attitude too much.

''We still really want to get something out of the season.

''We still want to play a brand of footy for four quarters and that's the goal every week and we'll keep working on that.''

Pittard is having the best season of his career and will feature strongly in Port Adelaide's best and fairest and All Australian calculations.

"All that's nice, but when the team hasn't performed the way you want it to, it doesn't really make too much difference,'' Pittard said.

''I just want to play a role for the team.

''I've been happy to be able to play consistently for most part of the year.

''There's been a few games where I've been a bit down along with other teammates.

''We're all just striving to play consistent footy and certainly I've enjoyed that part of it, but still disappointed with a few of the games we've played as a team and that's the most important thing.''

Pittard has taken on more of a leadership role in a youthful Port backline that has blooded the likes of Darcy Byrne-Jones, Tom Clurey and Logan Austin this season.
