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.

โ€œOne of their stars, he is a champion and weโ€™re not calling the end of his career of anything, but Gary Ablett played the worst 30 possession game Iโ€™ve seen for some time,โ€ he toldย SENโ€™s Crunch Time.

โ€œHe 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.โ€

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

โ€œTheir bottom end played pretty poorly," Brereton said.

โ€œYou didnโ€™t get much out of Lachlan Fogarty, Jordan Cunico, James Parsons, and Brandan Parfitt. Some of those boys are talented, but you just didnโ€™t get much out of them.

โ€œTheyโ€™re good enough (to make the finals), theyโ€™re a talented side. Iโ€™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.โ€

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