With the eyes of the world — and the expectations of a nation — upon them, Brazil fell behind 1-0 in the 11th minute against Croatia thanks to an own goal.
Twitter and Vine had a lot to say about this:
World Cup 2014 is the first edition in World Cup history to open the scoring with an own goal.
Well Done Marcelo. First Ever #OwnGoal By Brazil in WC. #OpeningCeremony #CafeRio #FootBallFever #BrazilvsCroatia
The #WorldCup2014 logo was very prescient. #firstgoal #owngoal #BrazilvsCroatia

This is the face you make when you score an #OwnGoal in front of the home crowd to open #WorldCup #BRAvsCRO #Marcelo
Someone tell him, he is playing for yellow team, not for red and white. #OwnGoal #Fifa2014

But Neymar responded with the tying goal a few minutes later, so all of Brazil can breathe easy.
