Not much history between these two sides on the pitch, but the two nations have a fractious relationship. Let's get geopolitical for a moment...

Relations soured during the Islamic revolution of 1979 in Iran, with the Middle Eastern country breaking off diplomatic relations with Morocco in 1981.

Those ties were reestablished in 1991 before King Mohammed VI of Morocco broke them off again in 2009.

Relations were renewed in 2014 but were severed again last month, with Morocco saying its decision was due to Iran's military support for the Western Sahara independence movement, the Polisario Front.

Morocco and Iran have never met at the World Cup.

In fact, they have faced each other only once previously, a game which ended in a draw.

Morocco face Iran at the Krestovsky Stadium, also known as the St Petersburg Stadium, the home of Russian Premier League side Zenit St Petersburg.

It's the second biggest ground being used at the World Cup, with a capacity of 68,134 and was opened just last year.

So yes of course Spain and Portugal are the two heavyweights in this group and they face off in Sochi later.

But a win here for either side, followed by a positive result against either Spain or Portugal, could see them cause an upset and reach the knockout stages.

Who's more likely to do so? Not familiar with either Morocco or Iran? Don't worry, plenty more information, team news and facts to follow.

Just as the first round of Group A games comes to an end, we begin the build-up to the start of Group B.

This might not be the biggest game in this group today...actually, it's the World Cup, they're all big games.

Welcome to live coverage of Morocco against Iran.
