Nigeria is a difficult country though, corruption is pretty rife (not saying it isn't in SA), and its got a pretty serious religious war going on in the northeast, City (Abu Dhabi) becoming a high profile in one of their clubs, could open that club up to being a target for the terrorists (imagine a team being kidnapped by them ?), particularly as Abu Dhabi are involved in the fight against IS in the middle east, who Boko Haram are allied to these days. I think that is a minefield best avoided for now, and in any case we could still take talent to a South African base. I would think having a foothold on the continent is more important.
