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:

5. Brad Crouch (restricted)

There were times when it looked like Crouch would be on the move this off-season, with reports emerging that he was seeking a long-term, $1 million-a-season deal.

Links were made to the Gold Coast Suns, with nothing materialising in the end.

But it could set up Crouch to be one of the prime movers in the 2020 free agency. The Crows look to be a sinking ship, and other than playing with his brother Matt, there isn't much keeping the Victorian at West Lakes.

He is sure to have a number of Victorian suitors next year and would be a great addition to any team's engine room.
