I doubt if the club would entertain a 1 year contract. If he's leaving, there's the door.Ask yourself this. Paul Connors also manages Petracca, Oliver and Salem at Melbourne. Who do you think Connors will want to please more, Freo or Melbourne??
If Cerra really cared about Freo getting fair compensation he would re-sign for 1 year at Freo and so he and Jackson will both be out of contract in 2022.
Freo offer Jackson that Cerra money with Melbourne having no chance of matching.
