Former Melbourne captain Garry Lyon says North Melbourne should not feel aggrieved by Andrew Gaff turning down their massive offer to join the club and deciding to remain an Eagle.

Gaff, who on Sunday re-committed to the 2018 premiers, turned down a potentially $8 million offer from North Melbourne, and speaking on SEN, Lyon said Roos fans should be happy their club is so open to chasing marquee players.

"You shouldnโ€™t feel aggrieved nor should their supporters," Lyon said.

"They should be happy that theyโ€™re in there swinging. There is flow on effectโ€ฆthere is ramifications.

"North Melbourne over the journey have forced Collingwood to up the ante for De Goey, they forced Sydney to up the ante for Issac Heeney, and may have lost Tom Mitchell in the process because they couldnโ€™t pay Tom Mitchell.

"Some of the big moves theyโ€™ve made have forced the clubs involved to get heavily involved and sometimes to their detriment."

North Melbourne have famously chased other marquee players with big money deals such as Jordan De Goey, Isaac Heeney and Dustin Martin only to be turned down.

It is believed the Kangaroos will once again attempt to lure GWS star Josh Kelly to the club over the course of the coming year.
