An Angel Di Maria strike two minutes before the end of extra time sent Switzerland home from the World Cup.
After what was arguably one of his worst performances in living memory, the Real Madrid man slotted home a composed finish after an assist from Lionel Messi in the 117th minute.
It almost was not enough to seal Argentina’s place in the quarter finals, however, as Dzemaili hit the post for Switzerland and then failed to convert his effort as it rebounded off the upright.
Argentina, like Germany against Nigeria only last night, struggled to make their mark on the game against lesser opponents as the Swiss defense held strong in the face of a formidable front line.
Lionel Messi went closest for the South Americans with a long range effort which was well saved by Benaglio.
Switzerland did threaten themselves, however, when Xhaka saw his well worked shot parried by Romero.
The match appeared to be heading inevitably for a penalty shoot-out as both sides looked fatigued, but Argentina went close once more through their captain, Messi.
But just as the game looked to be headed into the lottery of penalties, Switzerland lost the ball on the half-way line and were punished greatly.
Messi found the ball at his feet and he raced towards the Swiss defense with pace, only moments after looking dead on his feet.
He drew defenders around him, leaving Di Maria in space just inside the box.
The winger slotted home with an incredibly calm finish to send his side through to the quarter finals.
The result leaves Swiss hearts broken, and sees the men in red fail to reach the quarter finals since their appearance there 50 years ago.
Argentina will now play the winner of the Belgium vs USA match, which is the night’s other fixture.
