SYDNEY is eyeing a trade for North Melbourne midfielder Ryan Clarke after touring the young Roo through its facilities this week.

AFL.com.au understands Clarke is investigating his options and the potential of a move to the Swans, with the 21-year-old's contract at Arden Street set to expire on October 31.

WHEN DOES TRADE PERIOD START? All the key dates

Clarke is yet to renew his current deal at North Melbourne after penning a one-year extension to his initial contract during his first pre-season with the club in February 2016.

He has since played 40 games for the Kangaroos, including 19 this season.

As Clarke is not a free agent, any move for the youngster will have to be concluded via a trade. Sydney is currently in possession of one first-round pick and two second-round picks, as well as a fourth-round and a fifth-round selection ahead of November's NAB AFL Draft.

It could also leverage North Melbourne's interest in Nic Newman in any negotiations, with the Kangaroos meeting with the uncontracted defender earlier in the month.

Sydney is likely to try and bolster its midfield stocks during next October's NAB AFL Trade Period, with experienced onballer Dan Hannebery already requesting a trade to St Kilda.

North Melbourne is also set for a significant off-season, having already met with Port Adelaide wingman Jared Polec and Gold Coast midfielder Aaron Hall, as well as Newman.

West Coast's star free agent Andrew Gaff has also been strongly linked with a potential move to Arden Street.
