Couple of historical scoreline angles that i can't see being ignored...
(1) All 8 WC's that have involved the R16 format have delivered a 90 min 0-0 knockout result.
8 knockout games in and none so far.
To me, Uru/Fra & Swe/Eng would seem to be the biggest candidates to end the drought. I think the other two games will deliver at least 2 goals each. Cavani being out means Uruguay will more than likely PTB like Colombia essentially did and hunt for a counter attack goal to win in reg, otherwise settle for sudden-death football. Sweden usually plays England tough, and if Colombia can deny England any run-of-play goals, I see no reason why Sweden can't. Sweden's offense in turn has looked suspect, their one decent outing against Mexico involved the latter collapsing mentally once they conceded the first goal of what was a tight game til that point. Once again, as always, either game avoiding an early goal should set the stage for this historically 'due' result.
(2) edit: why the Uru/Por result escaped me, I have a slight inkling but the fact is it finished 2-1 making this angle redundant.
