Collingwood's premiership midfielder Dane Swan says everyone has a view on Gary Ablett's move to Gold Coast but it is "no-one's business".

Ablett revealed earlier this month he barely spoke with then-Geelong coach Mark Thompson following an argument in April over the Brownlow Medallist's playing future.

The two-time premiership star was Geelong's best player when they lost to Swan's Magpies in the 2010 preliminary final.

Ablett later signed with Gold Coast and attracted heavy criticism for walking out on his mates at Skilled Stadium for a lucrative deal with the Suns.

But Swan says Ablett deserves to be given the opportunity to follow his Queensland dream without his motives being constantly under attack.

"Football's very much an opinion sport," Swan told AAP on Thursday.

"Everybody's got an opinion about everything.

"If Gary thought that was the right decision ... it's no-one's business.

"It's good on him for what he did.

"He decided to leave and for what reasons? Well that's between him and his family and his manager I suppose.

"I hope he has a good career up there. They're going to be very good in a couple of years' time, so he might win a premiership up there."

Swan, who is in the same management stable as Ablett, says he expects Gold Coast to be "competitive" in their debut season in 2011.

"Gary Ablett is the best midfielder in the league and they've got (ex-Magpie) Josh Fraser who is a good ruckman," Swan said.

"Whether they finish in the top half is up to them."

Swan has one year left on his contract with Collingwood and is also expected to come under attack from rival clubs including 2012 debutants Greater Western Sydney.

Swan, 26, said he "absolutely" wanted to be a one-club player.

"I have a lot of good mates down there, with Taz (Chris Tarrant) coming back, he's one of my best mates," Swan said.

"I get to play with him for a couple more years. I love the footy club and I'm a Melbourne boy so ideally Collingwood is the place I want to be at."
