Geelong could target Eagles star Andrew Gaff in a trade for Tim Kelly, according to Triple M's Jay Clark.

Gaff has a clause to get out of his contract at the end of next season, meaning he could leave West Coast for nothing as a free agent.

The 27-year old knocked back offers to return to Victoria at the end of last season to re-sign with the Eagles.

However, Clark believes the Cats should "ask the question" of Gaff.

"The really interesting one for me, and I think this will really get some pace over the next couple of weeks, is Andrew Gaff," he said on Triple M's Dead Set Legends.

"We know what we went through 12 months ago. As I understand it, he's out of contract at the end of next year, and the Eagles don't really want to go through the whole hullabaloo again.

"If I'm Geelong, and I'm sure (Geelong recruitment manager) Stephen Wells is all over this, I'm asking the question."

Former St Kilda great Leigh Montagna posed whether it could be in West Coast's best interest to trade Gaff.

"Do you think maybe West Coast entertain trading Gaff with a year to run on a contract to get something for him, rather than maybe, he walks as an unrestricted free agent as a 28-year old at the end of next year? Do you think that's a possibility?" Montagna posed.

Clark replied: "The Eagles would be mad trying not to do that trade with Gaff now. There's really interesting conversations that will be happening at the moment.

"West Coast want to lock Gaff in for the long term. There's some chance that the Cats could pounce on that."

Montagna declared West Coast would win a Kelly-for-Gaff straight swap.

"Kelly is coming into the peak of his powers. Gaff's a wonderful player, but I'd take Kelly in my team."
