The Swans were reportedly seriously interested in Ladhams last year, before trading for then-Eagles ruck Tom Hickey.
Despite the success that came from acquiring Hickey, the 30-year-old is nearing the latter stages of his career and Sydney could once again be in the market for a tall.
Callum Sinclair (31 years of age) just signed a one-year extension at the Swans despite managing just four senior games in 2021, while Sam Naismith (29) has had a luckless run with injuries over the course of the past two seasons.
However, it remains to be seen whether the Swans have an interest in trading for Ladhams in 2021.
