Yeah, this World Cup is definitely interesting, in that there doesn't seem to be clear-cut favorites in the field. Even some of the teams that were favorites coming in (Belgium, France, Germany, Argentina, etc.) looked sluggish. Maybe that's just some nerves since it's still early in the tournament, but still interesting.
I know Belgium won 3-0 today but they definitely looked shaky at times before they ultimately wore out Panama and scored 3 second half goals.
Still got two games left tomorrow before the 1st set of group stage games are complete, but I think the Iceland-Argentina result AND Mexico-Germany results are the most surprising so far. Brazil drawing with Switzerland was also surprising I guess.
