Collingwood is reportedly interested in GWS pair Adam Tomlinson and Will Hoskin-Elliot.
The Herald Sun reports the Pies are interested in both players, who may seek fresh starts after limited opportunities this season.
The Pies are particularity keen to secure goal kicking midfielder, Hoskin-Elliot.
The 22-year-old, who is contracted for 2017, has played 52 games since being selected with pick No.4 in the 2011 National Draft, but has managed just two games this season.
Tomlinson, also recruited in 2011, has played 13 games this season, including the last eight matches of the year, to total 65 career games.
Meanwhile, Caleb Marchbank yesterday requested a trade, with Carlton the front runners to secure his signature, while Cam McCarthy will join Fremantle this off-season and Jack Steele appears likely to join the Saints.
