Was thinking along those lines, but he'd need to do more of an apprenticeship in the lower leagues or EU first I reckon...lest he become Moyes at MU.
He's done time with Brisbane and Melbourne in the lower standard A League.
He's had a team of, in theory, 'out of their depth' players and put a credible performance in the World Cup.
He's won an albeit 2nd tier International Tournament.
If push came to shove, both We and He could do worse.
