FOUR-TIME St Kilda best and fairest Jack Steven looks destined to end up at Geelong.

The Saints star has struggled with mental health issues which restricted him to just seven games this season.

He's contracted until the end of 2020 but the 29-year-old looks set to move closer to his family, as Cats list manager Stephen Wells explained to Melbourne radio station SEN on Tuesday.

"I think he wants to come to Geelong – I'm pretty sure of that, but he is still a contracted St Kilda player … it also depends on negotiations with his manager with his contract," Wells said.

"The way it's headed, he's a good chance to be headed to Geelong."

St Kilda is unlikely to stand in the way of a deal being done.

"We've spoken to the Saints. We can't do anything, really, until trade week," Wells said.

"The Saints have been very good in considering Jack's mental health situation, where he had to miss some games this year, and if it turns out we can do a satisfactory deal for all concerned, I think the Saints have made it public that they're happy to try and help Jack."

The Cats are still waiting on a decision from brilliant onballer Tim Kelly, who could seek a move back to Western Australia.

Meanwhile, Gary Ablett is mulling over whether he goes on for a 19th season.

Inside midfielder Charlie Constable struggled for game time in 2019 and was limited to seven matches, but won't be leaving.

"We had a good conversation with Charlie the other day. He wants to stay, so he's staying," Wells said.

Constable, 20, is contracted until the end of 2021.

Fringe big man Wylie Buzza's future is up in the air.

"We spoke to him the other day and said there's a chance that he'll still end up on our list…he might have some other options, but at the moment, he is out of contract, and I guess we'll just see how the next week or so plays out," Wells said.
