//...but I don't really want England to scrape in with just one win and a draw.//
Which shows the farce that such competitions as the World Cup are. England could lose 3-0 today and still finish top of their group. They could lose 5-0 and still qualify. That would be on the strength of one win, one goalless draw and one defeat.
It takes 48 matches and the thick end of two weeks to reduce 32 entrants to 16. A third of that number is all that should be necessary and once you lose, you're out.
