LIONS beware: the Power are planning to replicate their fierce approach to last weekend's Showdown against the Brisbane Lions at AAMI Stadium on Saturday night.

A physical Port Adelaide outfit harassed the Crows, almost into submission; last week with some heavy bumps and nearly came away with the win.

Power vice-captain Chad Cornes said it was one of the best performances he'd seen from his team in a while.

"We plan to play like that going into a game and I think we play our best footy when we do," Cornes said.

"You don't always see the big hits and guys getting stretchered off, and you never want to see that, but sometimes it happens.

"We say we want to play like that every week and some weeks we do and some weeks we don't, so I think it's all in our heads.

"I'd love to know the reasons why some weeks you bring it out and others you don't. We seem to against the Crows and now we just have to replicate that against every other team in the competition."

Port Adelaide, despite putting up gallant efforts against Adelaide and Geelong, is without a win after three rounds of the season. But Cornes said there is no reason to panic.

"We've obviously lost the three games, but they have been against three pretty good teams and two of the games we could've easily won.

"The Sydney game was really disappointing, but I was really proud of the way the boys played on the weekend. We just need to clean a few little things up and I think if we play like that most weeks we'll win."

The Power used Wednesday's main training session to hone their skills and, in particular, hitting targets inside the forward 50m.

Livewire Shaun Burgoyne watched his teammates from a stationary bike on the sidelines as he nurses an ankle injury sustained in the first half against Adelaide.

Port Adelaide has average just 12 goals a game this season, but Cornes portioned the blame on poor execution from the midfielders and defenders, rather than on the forwards.

"We know the talent is there [in attack]. In my opinion, they are one of the most talented forward lines going around," he said.

"The delivery from the midfield and defence hasn't helped those guys. In saying that, a few boys are down on confidence and haven't had the start to the year that they would've liked, but that changes.

"My game against Sydney was pretty ordinary and I bounced back the next week. It only takes a week to find your form."

Cornes remained tight-lipped as to which Power defender would get the job on Jonathan Brown, but the Coleman Medallist's size alone would suggest it will be a task for either Toby Thurstans or Alipate Carlile.

"I don't know who will get the job on him yet, but if we stop Jonathan Brown that will go along way towards winning," he said.

"Their midfield still has some really good players in there too and I'm sure Kane and Dom Cassisi will get a job. We really need a win and we want it pretty bad."
