Geelong coach Mark Thompson shortly after the win warned his young charges about complacency ahead of this weekend's clash with the Dockers.

Fremantle surprised Richmond with a 66-point hiding, led by new recruit Trent Croad who kicked five goals.

``I think we've just got to concentrate on next week,'' Thompson said after the match.

``I know the players are pretty close and they're a good young group of players who are working for one another and they'll just continue to do that.''

Thompson said while his side would go into next week's game buoyed with confidence, he warned that form in a young side was fickle.

``Form can be such an up and down thing with young teams,'' he said.

Poor disposal was still a feature of the game and Thompson said the side still had a long way to go.

``I think our kicking still wasn't great,'' he said

``There's just so much we can do better than what we did today.''

The win elevates Geelong to sixth on the ladder after being written off by the critics at the start of the season.

``They really didn't know anything about us and if they want to change their minds that's completely up to them,'' he said.

``They've just seen and been thinking we've lost some players, (David) Spriggs and (Garry) Hocking and (Justin) Murphy and these sorts of boys.

``Maybe it's a judgment based on not knowing who Cameron Ling is or not suspecting Bartel would come in and play the role he has, so I think it's very much understandable that they thought that way.''

As far as the young Cats have come in the past couple of weeks, Thompson said there was still a long way to go.

``I knew I had a lot of hard work at the start of the year and there still is a lot of hard work left,'' he said.
