Greatest football teams from Africa and Asia.

I've been researching football teams which have been considered the greatest teams of all time i.e. Brazil 1970, Barcelona 2008-2011, Santos 1962-1963, Manchester United 1998-1999, Arsenal 2003-04 etc. Most articles have come up with great European and South American sides but not many from Africa or Asia (or North America for that matter). So my question is what would people consider to be the best football teams ever assembled from Africa and Asia? It can be a club side or a national team.
