Once again, Argentina wins by just one goal.
Of the four quarterfinal matches, the one that really surprised me was Netherlands vs Costa Rica. Although I had expected Netherlands to win, I was quite surprised that no goals were made at all, which brought the match through extra time all the way to penalty kicks. (Now, of the 12 knockout stage matches so far, six have gone to extra time and three of those have gone to penalty kicks.) What most impressed me was Costa Rica's style of play that always seems to force their opponent into an offside.
Neymar's injury, specifically, is that his third vertebra was fractured. It's not serious enough to require surgery, thankfully, but he will not be able to play for a few weeks so it can properly heal. To say that everyone in Brazil is saddened by this news would be an understatement.
