FREMANTLE's loss to Port Adelaide followed the same script as the side’s previous four losses, but coach Mark Harvey believes better composure could turn things around.

Fremantle had a terrific first and third quarter at Subiaco Oval on Sunday against the Power and led by two points at three quarter-time, but was outscored six goals to one in the last quarter to go down by 28. Fremantle’s fifth consecutive loss after leading at three quarter time is an AFL record.

That is obviously of concern to Harvey, but his side still had as much of the ball in the last quarter, but costly Fremantle mistakes and the brilliance of Daniel Motlop and David Rodan was too much. Harvey now wants to see his players show the composure required to get their team over the line.

"Statistically you'll take what we had any day; it's the composure thing that's the problem. There wasn't a lot in any area of the game, but they did get their goals easier than we did," Harvey said.

"There wasn’t a lot in the clearances at stoppages, which was an area we focused on and in the end it was our lack of composure when going forward. That included skill level; decision-making and simple things like receiving a handball and not taking it cleanly, those things really cost you."

Harvey would not elaborate on what he did differently coming into the game or what he might do differently before playing the Brisbane Lions at the Gabba next Sunday.

Harvey said the Dockers’ final quarters against Port Adelaide and Carlton were better than the club’s final quarters against Geelong, Melbourne and the Western Bulldogs.

"We might have done something different last week that we don’t want to discuss and we might do something else this week. We'll do it internally whatever it is," he said.

"They are a resilient group and keep on coming whether you want to hear that or not. If we can just have better composure and they keep working on the things during the week that they need to improve then we will be a better side.

"We still had as much momentum in the last quarter, but they were just more polished. In the last two weeks we have had more opportunity to win the game than the last three weeks."

Aaron Sandilands had another good game in the ruck, with Rhys Palmer, Ryan Crowley and Kepler Bradley also terrific, but Harvey believes his forwards let the side down, especially considering Fremantle had 51 inside-50s to Port Adelaide’s 38.

"Our ability to dominate for two quarters and to force Port Adelaide to flood was a good sign," he said.

"The problem is you don’t want your ruckman kicking the biggest score in the team, he's doing everything. He kicked 2.3 and did well in the ruck, so he stood up but our forwards had quiet days."
