Angel Di Maria scored deep into extra time to give Argentina a 1-0 win over Switzerland and seal the South Americans a place in the quarter-finals of the World Cup.
With the score tied at 0-0 at halftime, the game then opened up in the second period as Argentina began to grab the momentum, and their blue and white clad fans brought the Corinthians arena to life, chanting and bouncing in unison.
The warning signs were flashing for Switzerland when Gonzalo Higuain went close with a header before Messi drove into the box and forced Diego Benaglio into a great save.
However, despite camping out in the Swiss half for long sections of the second half Argentina could not make the breakthrough and the 90 minutes ended scoreless.
After a tense 0-0 draw at 90 minutes and a scoreless first period of extra time, Lionel Messi broke quickly and released Di Maria, who swept the ball home before wheeling away in delight.
Blerim Dzemaili almost saved the Swiss when his header hit the post but Argentina held on and now face a quarter-final with either Belgium or the United States, who play later on.
Argentina looked the stronger side in extra time when Swiss legs began to tire and Di Maria curled the ball past Benaglio to seal the late triumph.
