Another day, another round of mouthwatering action.
After securing a 1-1 draw against the USA in their first Fifa World Cup match for 64 years, Wales will return to the Ahmad Bin Ali Stadium on Friday to take on Iran.
The two sides have only faced each other once before in men’s international football, with Wales winning 1-0 in a friendly match in 1978.
The referee for the match is Mario Escobar. The Guatemalan comes into the World Cup with plenty of major tournament experience, having taken charge of the Gold Cup final in 2019. A year later, he was the man in the middle for the CONCACAF Champions League final.
Following the results from the opening round, this is a huge match.
Wales would take a big step towards progression with victory but anything less than three points would leave them needing a result against England in the final group game to have any chance of making the knockouts.
Iran could be eliminated after just two games with defeat (if England also beat USA). However, victory for them would put them right back in the mix for a round-of-16 place.
