As I've said previously in this thread, my mail a few months ago was that he wants to live in Melbourne much more than any of the other capital cities and the fact that he has been closely linked to only Melb teams of late would probably be a sign that that mail was correct.
Not keen on living in Brisbane though and I have no doubt that other clubs would be offering him an equivalent deal, if not better.
I think it's just that he isn't any club's no.1 trade target and as such he has to wait and see how those clubs go with their no.1 targets (eg. Collingwood and Richmond with Treloar, us and Carlton with Carlisle), which they will need to sort out before they know how hard to go for Aish.
Once that's all sorted, I expect him to tel Brisbane he's out, unless he gets a bit affronted that he isn't anyone's no.1 target and says "stuff them, I'm staying", in spite of not liking living in Brisbane!
