It all depends on the clubs way of looking at it.
Marquee player rules state that a club trained player over 75k can be given the dispensation or another player who is on 150k. We could bring an Aussie over on 180k but have a club trained player on 130k, it’ll be more proportionate to give it to the club trained player.
Looking at it that way, we could have more than 150k left on the salary, as we haven’t really brought anyone in with a big salary after Merrin left (club stated Prior was coming to play in the team with Merrin). So they could have allocated that marquee player elsewhere to create more space.
