SYDNEY Swans midfielder Luke Parker is set to sign a contract extension before Christmas, his manager says.

Speaking to NAB AFL Trade Radio, Ned Guy said there was interest from other clubs but Parker was happy to stay with the Swans.

Parker, who turns 23 later this month, won the club's best-and-fairest last year when the Swans made the Grand Final and in contracted until the end of next season.

"He's going to have a good long think about it, but I think all signs point to Luke committing long-term with the Swans," Guy said.

Melbourne had not offered a deal to Parker, but after rumours emerged that the Demons had tabled a big contract they made contact with Guy.

"Once that rumour went around last week I don't think there was a club I didn't hear from.

"I spoke to (Melbourne list manager) Todd (Viney) once the rumour came out and I think he said, 'Look, if we're going to be rumoured speaking to him, we may as well'."

Geelong forward Josh Walker could be on the move, with Carlton having been touted as a suitor.

Mitch Clark and Rhys Stanley were picked up last year and the Cats are looking to pick up Lachie Henderson from the Blues in this trade period.

"Clearly Geelong has brought in some good tall talent over the last 12 months and look to be bringing in more this year," Guy said.

"We've probably just got to sit down and work out what this means for Josh."

Guy said Walker could be part of a trade to bring Henderson to Geelong.

"Potentially it could, if Josh says he'd like to look elsewhere, but at this point we haven't got to that stage."
