This season's free agency and trade period has officially closed and so it's time to look ahead to the biggest fish who could be on the market in 2020.

A number of stars will enter free agency who didn't make our list, including, Tom Hawkins, Ben Stratton, Robbie Gray, Bachar Houli, Josh P. Kennedy, Josh J. Kennedy, Shannon Hurn and Easton Wood.

However, due to age or just the sheer unlikelihood that they would leave their clubs, we've left them off our list in favour of guys who are either more getable or in their prime.

Here are the top 10 free agents of 2020:

9. Jack Viney (restricted)

Viney hasn't yet fulfilled his potential at the Demons, battling a number of injuries across his career.

There is some talk that Melbourne will hand over the captaincy to Max Gawn in the off-season, and if the club endures another disappointing season, it could open the door for Viney to seek a fresh start elsewhere.

The hard-nosed midfielder has career averages of 22.1 disposals, 5.8 tackles and 5 clearances.

He will likely re-sign with Melbourne, but could explore the market.
