North Melbourne are targeting Giants duo Zac Williams and Aidan Corr, reports Triple M'sTom Browne.

Williams will be a restricted free agent at the end of the season and is expected to be courted by a number of rival clubs with big-money offers.

Corr also becomes a free agent at season's end and is coming off a career-best campaign for the Giants as one of their most reliable defenders.

Browne believes the Roos will pursue both players.

"There's some good mail going around in my trade circles overnight that they're after a Giants pair - Williams and Corr," he said on Triple M's The Hot Breakfast this morning.

"There's a lot to play out in the free agency space. North obviously have gone for some big fish in recent years, they've come up short a number of times.

"This time, perhaps they'll land those two. There's a lot to play out there, but that's what is going on behind the scenes in trade land.

"A lot of the team still don't know how much money they can spend and how many people they can have on their list."
