Yes, all of these scores in the knockout rounds have been very low.
I understand that the World Cup at least in the group stage had the most goals scored in it since 1970. One TV pundit said maybe that is why it has been so good.
Some World Cup betting is only on the result after 90 minutes, not even the A.E.T., added extra time.
The announcers said the Swiss did very badly in their shootout vs. Ukraine in one of the recent World Cups. Be good to see someone win this straight up.
