PORT Adelaide vice-captain Ollie Wines says he should've been marking Geelong star Patrick Dangerfield when the Brownlow Medallist kicked the match-winning goal against the Power last Thursday night.

With the Cats trailing by four points late in the game, Dangerfield received the ball from skipper Joel Selwood and secured the two-point victory at Simonds Stadium.

Power midfielder Sam Gray was next to Dangerfield when the ruck was contested before losing sight of him.

"In an ideal world, I would've loved to have been on Danger," Wines told SEN radio on Tuesday.

"I was playing on him at stoppages for most of the game, but I got into the stoppage late; I was on (Zach) Tuohy when he had the shot.

"In terms of setting up, we were set up well and in a good position that if we didn't win the stoppage, to nullify it.

"There's a few things we didn't execute well, just lost our feet and that probably cost us a goal."

Wines said the Power had learnt several important lessons from the game ahead of this Thursday night's clash with Hawthorn at Adelaide Oval.

"We've had to review the game, and there are probably a few hard truths that cost us the four points," Wines said.

"One of those was their ability to get lead-up marks through the midfield.

"They had a lot of uncontested marks that got them field position and got them close to goal.

"The way we moved the ball was a little bit stagnant, it wasn't quick enough to get it down to our forwards."
