New Zealand will play their first World Cup game in 16 years with much of the planet watching what is surely the biggest event of the group stage. But little attention will be on whether New Zealand can record their first World Cup win with Iran their opposition on 15 June. As well as all the headlines and anticipation, the global spotlight adds an extra layer to the challenge for New Zealand coach Darren Bazeley and his team.

Ever since the US and Israel attacked Iran on 28 February, there has been uncertainty surrounding this World Cup fixture in Los Angeles.

There were conflicting signals whether the Islamic Republic of Iran would allow the national football team to travel to the home of its attacker, and whether the US would welcome Team Melli. With kick-off now weeks away, it appears the game will go ahead as planned. Still, there is the possibility of protests by the large local Iranian population in “Tehrangeles”, many of whom fled the 1979 revolution, and acts of defiance by players. It’s more than a football story.

New Zealand, who also face Egypt and Belgium in their group, are very much the supporting cast in this drama. It is an unusual situation for any team to be in but that has been the case for the past three months with Bazeley never quite sure who the opposition would be for New Zealand’s biggest game since 2010.

“Right now we’re still continuing as though we’re playing Iran,” Bazeley said in March. “They’re the team that qualified and we got drawn against them. That’s still the fixture and until we get told otherwise, we’ll ‌continue ⁠with that preparation. Obviously, if things change, then we’ll deal with that.”

Nothing has changed yet despite Iran’s request that the game be switched to a different country, leading to the prospect of New Zealand having to play in Mexico before heading to Vancouver for their final two group games. Fifa did not agree to that but have given the go ahead for Iran to switch their training camp from Arizona to the Mexican border city of Tijuana.

So, as it stands, it is Iran in LA. If that question is almost answered, then it now remains to be seen what kind of mental and physical condition Iran is in. There has been no domestic league action since the war in Iran started. Team Melli played two games in March behind closed doors – a 2-1 loss to Nigeria and then a 5-0 victory over Costa Rica. The players sang the national anthem with varying degrees of enthusiasm. There is little doubt that they are under considerable pressure.

Amid all this uncertainty, the All Whites (official nickname of the New Zealand team) have a game to prepare for but their World Cup opener may not be as difficult as some think, according to Jahanyar Mohebbi, former assistant at Persian Gulf Pro League team Foolad FC.

“Coach Amir Ghalenoei and his [Iran] staff will not change a lot, there will not be surprises,” Mohebbi, now with Chinese champions Shanghai Port, told the Guardian. “Iran are not an easy nation to play against … Iranian players are absolutely physical, always play direct. New Zealand will face a team that will be set in a low block and will try to get behind you on the counterattack.”

Mohebbi has seen how Uzbekistan, who have developed quite a rivalry with Iran on the pitch in recent years, have learned to deal with the threat. In the last six meetings, Team Melli have failed to defeat the central Asians. “Look at how Uzbekistan play against Iran and deal with the long balls and set pieces,” he said. “It will be similar.”

There are other issues for Iran. Many of the players haven’t played a competitive game for months. “New Zealand have players in Europe at a high level and if they can put Iran under pressure, if there is intensity and pressing, the Iranian team can struggle,” said Mohebbi.

And then there is the politics. Sardar Azmoun was left out of the squad after posting social media messages that did not go down well in Tehran. Other members of the team have reportedly been pushing for the inclusion of the former Roma and Bayer Leverkusen striker but as things stand, Azmoun remains on the outer. It all adds to the chaos. “There are a lot of things going on that are not under the control of the coaching staff,” said Mohebbi.

New Zealand will share the pitch and some of the global spotlight in Los Angeles in what should be an unforgettable occasion no matter the final score.
