OGS has spent enough time in English football to know that we are a big club; not a very big club like redscouse or massive club like manure, but never the less a big club. If OGS had thoughts of coming back to England then the second he heard about Villa's interest he would have been weighing things up:
Decent size club? Well yes, way bigger than half the Premier League and as big a club as he could currently hope to manage.
Controversially, are Villa a big enough club that if he does really, really well with he'd be considered for his top job? Yes; something that can't be said about the likes of Wigan, Swansea, the boggies and Reading.
Is it reasonable travelling distance from the training ground to his established roots in Cheshire? Yes, just an hour on most days.
Other than Villa and Everton, I'm not sure who else ticks his boxes.
Whether it ends badly, he performs miracles and leaves in 3 or 4 years or does well and stays for a decade; I'd still like us to give him a go. It would be a gamble but I'd rather play strip-poker than bet on the time it takes for paint to dry.
