Adelaide midfielder Brad Crouch wants to join AFL rivals St Kilda.

Crouch is understood to have told the Crows he wants to be traded to the Saints as a restricted free agent.

Adelaide’s 2019 club champion fell off-contract with the South Australian club at the end of their season and has been seeking a five-year deal elsewhere.

Under free-agency rules, the Crows can match St Kilda’s offer for Crouch which would then force the clubs into a trade deal.

If Adelaide doesn’t opt to match the offer, they will receive draft pick compensation from the AFL.

The Crows, who have been contacted for comment, could be given pick No.2 at this year’s draft if the Saints’ offer is more than $700,000 a season.

Adelaide also have the first pick at the draft after finishing last this season.

Crouch earlier this month was given a two-match suspension by the AFL after being caught in possession of an illicit drug, believed to be cocaine, in late September.

Crouch’s future in Adelaide has been in question since the end of last season when he was linked with a move Gold Coast, only to remain at the Crows.

The 26-year-old this year was on the recruiting radar of Geelong as well as the Saints.
