Former North Melbourne and St Kilda midfielder Nick Dal Santo has some concerns for Geelong ahead of the 2019 season, suggesting the Cats don't have room to grow into a top side and contend for the premiership.

Geelong have struggled in the finals in recent seasons, with a 3-9 record in September since 2011.

They were eliminated by Melbourne in the first week of the finals last season, and despite all their talent, Dal Santo can't see where the side improves this campaign.

“I have concerns with the Cats,” Dal Santo told SEN Breakfast on Monday.

“Ultimately, I respect what they’ve been able to do, to be able to regenerate and rejuvenate from within and with trades.

“I can’t see them getting any better and that’s my concern when I look at the Cats’ list.

“I don’t think Joel Selwood can play any better, I don’t think Tom Hawkins can play much better, Patrick Dangerfield is arguably the best player in the competition.

“When you put that all together, I’m not sure where the next crop of exciting young players that will have a sustainable impact from week to week will come from.

“I think they can play finals but when it gets to the real pointy end, I don’t think they have enough arsenal just to get the job done when they have to.”

Geelong have a tough start to the season, facing Collingwood (A), Melbourne (H), Adelaide (A) and GWS (H) over the first four rounds.
