Iran successfully conquered Wales in the final minutes of the match, of course it was very, very painful for Wales in tonight's match, because they were mired in the lowest position, and it seemed impossible for Wales to qualify for the next round, because they will meet England in the next match, and Iran have a chance to qualify for the next round, if they win or draw against the USA, they will be sure to qualify for the next round, the competition in group B is really very fierce to watch.
Yeah, it's a surprise that Iran managed to defeat Wales, and it looks like you're right that the outcome of the Iran-USA match will determine who will finish second in Group B. Although I think neither the USA nor Iran will be able to go beyond the next round because their opponent will be the winner of Group A, and it will most likely be the Netherlands.
