The Kangaroos are reportedly interested in signing out-of-contract GWS defender Aidan Corr.

The 26-year old is a restricted free agent at the end of the year, and according to AFL.com.au, won't make a decision on his future until the season is finished.

The Victorian has been important in defence for the Giants this season, but could potentially be offloaded to make space in the salary cap.

In the middle of August, Triple M's Tom Browne reported that it wasn't just Corr the Roos were interested in, but also midfielder Zac Williams.

However, both are restricted free agents, so the Giants could decide to match North Melbourne's potential offers.

And if reports are correct, then GWS would ideally be looking to do exactly that should an offer come in for Corr.

Corr signed a two-year-deal with the Giants in the middle of the 2017 season, which secured him until the end of this season.

North Melbourne have made it no secret that they're in need of defensive reinforcements, with their head of player personnel Scott Clayton telling AFL.com.au back in April that they were in the market for defenders.

The Roos are set for an eventful off-season, with a clean-out on the cards in order to improve on their torrid 2020 season.

Corr's defensive versatility would be perfect for North Melbourne, with a capacity to play on a range of opponents from Anthony McDonald-Tippungwuti to Josh Kennedy.

With a reported 23 players out-of-contract at the end of 2020, the Kangaroos could have some money to play with in the trade period.
