ST KILDA has no interest in luring Brownlow medallist Nathan Fyfe to the club in 2018, says football manager Jamie Cox.

A restricted free agent at season's end, the Fremantle superstar has been linked with a move to the Saints as they have sufficient salary cap room and a perceived need to add class to a young and promising list.

Cox told SEN on Tuesday morning Fyfe wouldn't be wearing red, white and black next season.

'We're certainty not chasing Nat," Cox said.

"I think I can confirm that, and to be honest, I'm not exactly sure how hard the chase was from the start."

However, when asked about Richmond's Dustin Martin and Giant Josh Kelly, Cox acknowledged the Saints were interested in luring established talent to the club.

"We've been out there publicly to say that this stage of our list development that we'll happily enter these discussions, but (negotiations) won't play out publicly," he said.

Whether star veterans Nick Riewoldt and Leigh Montagna will play on is also up in the air, with Cox revealing talks with the pair were yet to begin.

"Those conversations start at the back end of the season, and I know in both their cases they're just determined to play strong footy and hopefully get us into finals," Cox said.

'It's not really my call (on new contracts), it's a club call.

"I know this decision will be made in the best interests of the club, so it's something we'll sit down as a group and determine in discussion with Nick, Joe (Montagna) and their management."
