FREMANTLE coach Mark Harvey is focused on trying to upset Geelong this Saturday, but couldn’t resist biting back at his Port Adelaide counterpart Mark Williams in defence of midfielder Josh Carr.

Williams has talked of how he would consider taking Carr back at his club at the end of the year, but Harvey quietly suggested that he should keep his mouth shut.

Harvey said he was pleased with Carr's last quarter against Essendon before the break and is confident he won't be looking to leave Fremantle.

"We might be starting to see him move into some of the form that we know he can play up to," Harvey said.

"Mark (Williams) has advertised a lot over the last couple of years about who he wants to come to Port Adelaide and he has to understand that it doesn’t work," he said.

"He's tried Pavlich, he's tried Schammer and now he's trying Josh. The smarter clubs do it behind closed doors. It's not something you like to deal with, but that's Mark."

Harvey says he will talk to retired champion Peter Bell about a possible coaching role, but in the meantime his attention is on his team's meeting with the reigning premiers at Skilled Stadium.

Geelong has demolished West Coast and Adelaide on the road in its last two games, but Harvey is confident his side can do well.

"I haven’t seen a side do that on the road two weeks in a row, so they are causing a bit of carnage. All I can say is that they've been awesome and that's where they are at, but we are here to ruin that," he said.

"As a coach I'm never daunted by who we play. All you can do is instill the belief in the playing group of what you want to do, and that's what I'll be doing."

Fremantle hosted Geelong on Anzac Day and was unlucky not to win, and Harvey believes the conditions might help Freo this time around by hindering the Cats' ball movement.

"The circumstances are different and Geelong is in better form than last time we played them," he said.

"Down at Geelong it could be raining and wet, so that could slow them a little. We have an enthusiastic young group that are willing to put enough pressure on them, though, and if they have the right intent about them we'll be in the game."

It's only two days removed from Bell's retirement, but in the coming weeks Harvey will see if he would like to be involved again at some capacity.

"I'll talk to Peter over the next couple of weeks about whether or not he's interested in moving into coaching," he said.

"He might also be able to do some mentoring and teaching guys facets of the game that he excelled in. He might just need a break from the game."
