ADELAIDE midfielder Richard Douglas says there's one more way that Crows players can honour their late coach Phil Walsh: defeat arch-rival Port Adelaide.

Douglas believes an emotional memorial service for Walsh on Wednesday offered grieving Crows players some clear air to again focus on football.

"It was a great celebration of Walshy's life and now it's about trying to play the way he wanted us to play, especially this week," Douglas told reporters on Thursday.

"You will always remember Phil and enjoy the times that we had together.

"... For us now, it's about this weekend and performing and getting the job done, as he would say."

Douglas said concentrating on football had been tough since Walsh was allegedly murdered by his 26-year-old son on July 3.

But the experienced onballer said Crows players had now narrowed their focus to Sunday's grudge match against Port at Adelaide Oval.

"There's a lot more clarity among the playing group," he said.

"It was really tough last weekend and at times personally I found it hard to concentrate on the game of footy.

"But this week at training there has been a lot more clarity, a lot more focus on the game plan and playing footy itself.

"It's all about winning for us (against Port) and I'm sure it 's that for them … where we are on the ladder – both clubs – it's so important to get a win.

"We want to get our season back on track … we're still in a reasonable position, I think our destiny's still in our own hands.

"If we can win enough games we'll definitely get there and we can have an impact."

Both the Crows and the Power will run out through a joint banner on Sunday, which Douglas said was a "nice touch".

The midfielder has no doubt that his side is capable of beating Port and said it would have won the Showdown earlier in the season had it not been for its inefficiency when moving forward.

The Power won the game by 24 points, despite Adelaide driving inside 50 71 times to 42.

Jay Schulz booted 5.1 and Patrick Ryder three goals straight in the 18.7 (115) to 13.13 (91) score line.

Accuracy in front of goal has been discussed at West Lakes and Douglas backed the club's forwards to deliver on Sunday.

"We should have won that game earlier in the season … we did control a lot of the game but we just couldn't get the score on the board," he said.

"That's something we've looked at already and we need to be more efficient going forward.

"It's a great challenge for us and we're definitely up for it."
