I think it was pretty obvious from the moment he was relieved of duty from Parra and headed over to the UK on short contracts that this was happening. I remember stating it would happen pretty much straight away. The fact that his wife is from here helps, and I'm lead to believe just recently they have purchased a home in North Coogee (just south of Fremantle). That's a fair way from HBF Park and Optus Stadium, and even further away from Malaga, but close to the supposed training facilities in Beaconsfield (old Fremantle Roosters home ground) and it's a property in WA, so I'd guess it makes sense.
So, for mine, it was always happening, and there aren't many former NRL coaches floating around with his experience. I don't mind the idea of it, personally.
