Sydney coach Paul Roos says he 'loves' Barry Hall and wants what's best for the controversial forward - even if that means the 32-year-old plays on at a rival AFL club next season.

Hall's AFL career appeared all but over on Monday when a fed-up Roos questioned the former captain's commitment after yet another brain snap, this time against Adelaide defender Ben Rutten.

However, in his regular column for Fairfax Media on Friday, the Swans stalwart, who is out of contract at season's end, confirmed retirement is not his preferred option and refused to rule out ending his career with a new AFL club.

"I'm not stupid to think I am going to fully redeem myself now for some of the things I've done, but I want to at least finish on a good note, whether that be at the Swans or possibly at another club next year," Hall wrote.

"The easy thing to do would be to walk away and take up boxing. But what would I be? Barry Hall the boxer, but also Barry Hall the disgraced ex-footballer."

"The perception of me might not change drastically ... but I want to go out with some good games under my belt and prove my worth as a footy player."

Roos, speaking at the SCG on Friday, admitted he was not yet sure what the future holds for Hall, but said he would not turn his back on the troubled veteran.

"We love 'Hally' - we do," Roos said.

"We love him as a person and we love what he's done for this footy club."

"Since I arrived in 1995 I was fortunate to play with Tony Lockett and I've seen some great players come and go through this footy club."

"Hally's revered at this footy club and whatever happens we'll certainly take into consideration Barry hall as well as the footy club."

"What we don't want to happen is either party to walk away bitter ... so that's why we're going to take our time with the process."

"I want a positive outcome for the footy club and for Barry Hall."

But Hall, who was slapped with a two-match ban by the match-review panel on Monday, would not rule out severing ties with the club before the end of the current campaign.

"I could stay here at the club, hope they don't sack me, and return to footy in two weeks after my suspension, be it in the seniors or the seconds," he wrote.

"But the other option I need to consider - and one which naturally would be a massive decision to make - is whether it is the right time for me to finish up at the Swans."

"By that I don't mean retirement. I mean walk away from the club, not footy. It could give me a break I might benefit from and freshen me up for a crack with a new club next season, and at the same time give the club a break from Barry Hall."

Roos said he would not think any less of Hall should he decide to continue his AFL career in enemy colours.

"If he plays again next year and it doesn't happen to be at this footy club I'll be the first one to ring him and wish him all the best," he said.

"But I genuinely stand here today and don't know what's going to transpire."
