That was a different sport with nearly opposite ramifications for victory and defeat.Teams just don't think like that. I'm betting the English and Belgium players believe that can compete and beat any team in the tournament. Old school Bowden days: anytime, any place.
I'll agree that these backups on both sides aren't out there to embarrass themselves on the world stage, however it would be naive to think their coach isn't aware of the bracket.
This is more aligned with a late season NFL or NBA game where you know a loss gets you an easier playoff match up and you just casually tank or play not to win.
