Honestly, if he hasn't got the Aussie job by then (and I can't see it happening given their current obsession with all things europe) I would be quite happy if we offered him the job once our current world cup cycle is over (either this year or next). Not sure how popular the job our job would be for good european manages (given our lack of budget), so would possibly be a good option.
The issue above (time to drill the system) may be an issue, but its an issue for any national team coach to a greater or lesser degree.
