Iran coach Carlos Queiroz has called on Nike to apologise to his team after the USA sportswear firm said it could not supply the players with football boots for the World Cup because of sanctions.
The two sides are in Group B along with Spain and Portugal, so both will be eager to earn points off the bat before facing the two European powers.
Both teams face tough tests Wednesday, as Morocco will play Portugal and Iran will face Spain.
"No matter what happens on the pitch I want my players to leave the pitch with their head up", said Queiroz. We love to deal with these moments of pressure because this is what it is all about.
"We want to celebrate and it's our responsibility, that's why we are here in Russian Federation".
Team Melli, who have qualified for the consecutive World Cups for the first time, are making their fifth appearance in the World Cup finals, however the Persian have not yet advanced to the knockout stage. "We know their team very well but I suspect they know very little about us". Pacific Time at Saint Petersburg Stadium in Saint Petersburg, Russia.
It's hard to lay too much blame at the door of the Moroccan medical team, who clearly didn't have the first inkling of how to safely assess the nature of their player's injury. We have addressed this concern to Federation Internationale de Football Association and the minimum Nike should do is to apologise to them (Iran's players).
Herve Renard's well-organised team extended Morocco's record of never having won their opening game in the tournament despite dominating the match and carving out opportunities to score either side of half-time.
