Lionel Messi moves up to 38 shots now in his World Cup history. However, just 2 goals.
Seven minutes until the break, and Iran are holding firm.
Argentina have the ball 40 yards out, and Iran have 11 players behind the ball. That's the state of this game so far.
Another free kick to Iran on the left flank... and they win a corner! A shock goal before half-time, perhaps?
Close for Jalal Hosseini again!
The defender gets up well at the near post to meet Ashkan Dejagah's corner, and should have put Iran ahead! Instead, he heads wastefully over.
Higuain whips in a cross from the right and Alireza Haghighi hold it well - he's had a great half.
Reza Ghoochannejhad delights the crowd with some lovely turns in the centre of the pitch! But he then loses possession, and Argentina have another corner.
Federico Fernández meets the ball this time, but his header, like the rest, is well over.
