North Melbourne reportedly made a multi-million offer to Sydney young gun Isaac Heeney during the recent trade period.

The Roos offered Heeney over a million dollars a season according to Channel Seven’s Tom Browne, with the club also a chance to pursue the 20-year-old star again at the end of next season when he comes out of contract.

However, the Roos had the offer knocked back by the Swans.

He averaged 16 disposals, 4.7 marks and 3.8 tackles in 2016.
