SAINT PETERSBURG, Russia (AFP) — Iran’s players stormed the pitch at full time as if they had won the World Cup rather than just their opening match, after an own goal from Morocco’s Aziz Bouhaddouz gifted them a dramatic 1-0 victory yesterday.

Wasteful finishing looked to have consigned this compelling contest at the Saint Petersburg Stadium to a goalless draw, but Bouhaddouz’s mistake in injury-time means Iran emerge as the early challengers to Spain and Portugal in Group B.

Iran coach Carlos Queiroz, once of Real Madrid and Manchester United, insisted the chaos that has engulfed Spain this week offered no boost to these teams’ chances, but this victory certainly cranks the pressure up a notch.

When Bouhaddouz nodded in at the near post Iran’s substitutes could not resist rushing onto the field, and when the final whistle blew moments later they were sprinting over again in delight.

Morocco should at least take heart from a blistering first half an hour, during which their zip and zest deemed them virtually unplayable. But Hakim Ziyach, Ayoub El Kaabi and Mehdi Benatia all failed to capitalise.

Instead, Iran showed the same grit that had frustrated Argentina for 91 minutes four years ago, but while Lionel Messi was the difference that day, this time it was their turn to snatch a last-gasp winner.

Their build-up had not been smooth. Nike had blocked the players’ supply of boots four days previous, while further back friendlies against Greece and Kosovo were cancelled.

It gave Queiroz good reason for positioning his team as the group’s outsiders, but both teams had cause for optimism after his side strolled through 18 games of Asian qualifying without defeat while Morocco were unbeaten too, with the added coup of not conceding a single goal.

Morocco’s fans, at a World Cup for the first time in 20 years, belted out their own national anthem and then applauded Iran’s, the 67,000-seater arena a sea of red and white and buzzing with the hum of vuvuzelas, in a throwback to the 2010 World Cup in South Africa.

The only shame was the large number of empty seats at kick-off, with many supporters still queueing to get through security 15 minutes before start time.

Morocco started brilliantly, hounding Iran’s every touch and swarming forward with such ferocity that on the line, Queiroz spent most of the opening 20 minutes urging his players to pause and take a breath.

The only surprise was Morocco were not ahead as Ziyach kicked the air from a well-worked corner, El Kaabi sliced wide, and a penalty-box scramble saw shots from Younes Belhanda and Benatia blocked.

The onslaught finally eased after half an hour, and by the interval Iran had not only survived but finished the stronger, Sardar Azmoun, the “Iranian Messi”, spurning a one-on-one after a scintillating break.

Perhaps tired from the first period or, more likely, reminded of their defensive duties during the interval, both teams were more cagey after the restart.

They each made substitutions as the game drifted past the hour, and the closest it had come to a winner was when a fizzing Ziyach drive had to be tipped around the post by Ali Beiranvand.

Queiroz and his opposite number Herve Renard were involved in a touchline scuffle that was quickly resolved before the real drama arrived, moments later.

Bouhaddouz could not see what was behind him when a whipped free kick came in from the left and he panicked, diving to the ball and heading it inside his own near post.
