Min 52: Ronaldo takes the penalty but Beiranvand saves it.
WHAT A SAVE!!!
Min 51:VAR points it to the spot after a foul on Ronaldo! Yellow card for E Hajsafi
Second-half starts!!!
Half-time report:Iran managed to frustrate Ronaldo and Co till the dying moments of the first-half but one fine moment by the super-talented Ricardo Quaresma gave the Portugese the much needed goal against the stubborn Asians. The beautiful goal is the only difference between the two teams as Iran are going all-out in order to secure a spot in the Group of 16. Although, Potugal look a different side in this match as they controlled 71 per cent possession but struggled to open the deadlock for a good 45 minutes of the first half while Iran looked dangerous with the counter attacks and almost managed to score in few instances. Rui Patricio made a few crucial saves to keep the sheet clean and Iran need to continue their counter-attacks if they want a positive result from the match.
With Spain and Morocco tied at 1-1 at half-time in Kaliningrad, Portugal are currently in the driving seat in Group B as it stands. If it remains so, they will set up a tie with tournament hosts Russia while their neighbours will have to face a resurgent Uruguay in the knock-out stage.
Trivia: Ricardo Quaresma became the oldest player to score on his first World Cup start (34 years, 272 days) since Yahya Golmohammadi for Iran against Mexico in 2006 (35 years, 84 days)
