Italiano said this yesterday, post game. Old's ability will only be fully recognized in NZ, once he's overseas somewhere killing it.
What i find impressive is this kid is supposedly carrying an ankle injury which needs rest to fully heal, yet he is still playing 90 and beating players for fun.
Edit - just before the 7 min mark in news conference, Chiefy says Old is fine now
