Hope like hell its not us would be a big step back im afraid 3 years at least to late. Would imagine Talay would prefer a younger Kiwi or Ausdie rather than him.
The only young Kiwis in the reckoning would be Waine (already in the squad), Logan Rogerson (probably miles from A League level fitness as he returns from a broken leg) and maybe Max Mata in Switzerland.
Waine still doesn't look ready (and may never be).
If Nix can't sign that Tomer Hemed or someone similar, they would at least have to consider Brockie. Knows the league well, and you couldn't totally rule him out of just suddenly having a 10 goal season purple patch. Sure more likely he'd be average, but is always the chance he could bang in few worldies. He'd be cheap, and as long as he was motivated plus fitted in with the playing style/setup you'd have to consider him.
Even if Nix could sign a Hemed, Brockie could still be a handy back up, again if was cheap. I'm not really sure about Waine.
