Why would you sell your rental now and not list him to sell before next update after Cup final? Even if fish had not got him seems a funny move to me.
Wanted to save 200k from Luster's salary I guess. The Winners spent 200k for a chance to win the Cup. Anyone in his position would've done the same. The added irony of beating your opponent with his own player was an extra incentive.
I just simply used the cash sales from Luster's transfer to buy the refs. It was 8 versus on 5 on the court all game.
