Coach Nathan Buckley said the Pies decision on Kreuzer was "still unresolved", confirming recent reports that the club has the 26-year-old big man on their radar but are weighing up whether to pursue him.

Collingwood already has three ruckmen on its list - Brodie Grundy, Jarrod Witts and American import Mason Cox - but could yet target Kreuzer during the player exchange period should the former No.1 draft pick leave the Blues as a restricted free agent.

"We have and are looking at Matty Kreuzer. We are still assessing whether it's a fit for us [and] he's assessing whether we're a fit for him," Buckley said Fox Footy's AFL360 on Monday night.

"And Carlton is still in the mix as well because he's a restricted free agent.

"That's ongoing and hasn't come to a conclusion."

Buckley said ruckmen Grundy and Witts remained "long-term players" for the club.

It comes as reports surfaced on Tuesday that the Pies were closing on a new deal that would secure the services of No.6 draft pick Matt Scharenberg for a further three years.

Buckley also said on Monday night that the club was confident it would facilitate a trade for Greater Western Sydney star Adam Treloar, who last week formally told the Giants he wanted to be traded and nominated Collingwood as his preferred home.

"We've begun conversations with them [the Giants], but in the end, the player generally gets his wishes," Buckley said.

"We've had ongoing dialogue with Adam's management and now with Adam, and I know him from coaching him in the under-16s," he said.

"We look forward to … welcoming him to the club for the rest of his AFL career."
