Adelaide midfielder Brad Crouch has impressed over the course of the 2019 season after missing the entire 2018 campaign through injury, and his form this year has caught the eye of some rival clubs.

According to The Advertiser, St Kilda is one of a number of Victorian sides monitoring Crouch's contract talks, with the midfielder to become a restricted free agent at the end of 2020.

For now, Crouch's management company W Sport and Media have told The Advertiser the ball-magnet is happy to wait for the Crows to make the first move regarding an extension, but with a number of other teammates coming off-contract at the end of this season, Crouch's new deal may have to wait.

Alex Keath and Hugh Greenwood will both be asking for healthy contract extensions, while the Crows will also have to work on a new deal with Matt Crouch in the next 12-24 months as well.

Keath and Greenwood may need to consider Victorian interest as well, with the defender the target of a big-money deal from Melbourne, while Greenwood is reportedly on Hawthorn's radar.

Jake Kelly's deal also runs out at the end of the season, as well as the contracts of veteran trio Richard Douglas, David Mackay and Sam Jacobs.
