One way you could do a full world cup in the future is you give each of the 20 teams a random number , then once you have 20 ( or less ) participants you ask them each to pick a number out of 20 at random , obviously not counting numbers picked , & the corresponding team is their team .....so basically a lucky dip , i wouldn't be fussed getting Nambia , i'd just see it as a challenge, a bloody hard challenge lol but fun non the less.
