Hawthorn legend Dermott Brereton has bashed Geelong star Gary Ablett's performance on the weekend, labelling it as 'the worst 30-disposal game I've seen in some time."

The dual Brownlow Medallist broke an AFL record for the most ever 30 disposal games during his side's tragic two-point loss to the Western Bulldogs, but Brereton thought he had minimal impact in the contest.

“One of their stars, he is a champion and we’re not calling the end of his career of anything, but Gary Ablett played the worst 30 possession game I’ve seen for some time,” he told SEN’s Crunch Time.

“He fumbled all night and had very poor gains. But he is going to strike back within a week or so and be exceptional once again.”

Brereton says Geelong's second-tier needs to step up for the eighth placed side to get their season back on track.

“Their bottom end played pretty poorly," Brereton said.

“You didn’t get much out of Lachlan Fogarty, Jordan Cunico, James Parsons, and Brandan Parfitt. Some of those boys are talented, but you just didn’t get much out of them.

“They’re good enough (to make the finals), they’re a talented side. I’m starting to get a little bit concerned for them between their top players and the blokes who are coming in 16 through to 22.”

It won't get any easier for the Cattery, who travel to Sydney to face the Swans on Thursday night.
