Fremantle coach Ross Lyon has blamed himself for his side's poor showing against Geelong, saying that he didn't prepare the Dockers well enough.

That wasn't to say it was the only reason Geelong ran out 42-point winners, as Fremantle conceded 7.2 from turnovers in just the first half alone.

Lyon admitted the turnovers weren't ideal, but did say blame his own efforts for failing to prepare the Dockers to ward off the Cats' pressure and spread in transition.

"(Turnovers) happened early and they are not ideal, but that wasn't the issue," Lyon said.

"I'm probably a little disappointed in myself. I could have prepared them for a couple of Geelong mechanisms they do well.

"They got back on us really well, which you expect AFL sides to do, but you can certainly put yourself in a better position to deal with it.

"And then I thought on transition, they were out. So, we weren't handling them getting back on us and we weren't handling when they got it.

"That's disappointing and can be a bit of work rate but a fair bit of positioning. I will take full responsibility for that.

"I know, within that performance, I see a fair bit of potential in us and a fair bit of hope.

"I know we're better than that."

Aaron Sandilands (48 hit-outs) and Nat Fyfe (28 touches) both did their bit for the home side, but Lyon will need to get the best out of the rest of his midfield if Fremantle are to win some games this season.

"The midfield – I think we can all get better, but I think everyone is saying that," Lyon said.

"There's a bit of life there. I expect them (Geelong) to be at the pointy end, I would think.

"The first one (game) I would've expected us to perform better so we walk away disappointed."
