The final scorelines reflected the reality of football, however – namely that domination does not always bring victory with it. To keep their qualification hopes alive, both sides will need to be sharper in front of goal when they face off on Wednesday.

The only side in Group C never to set foot in the knockout stage, the Iranians will achieve that goal with a game to spare if they defeat Zambia and the other match in the section ends in a draw.

4 In their opening match, South Africa fielded a side in which every player bar goalkeeper Mondli Mpoto was less than 5’7 (1.70m) in height. In contrast, the only Italian player to measure under 5’11 (1.80m) in their first game was midfielder Nicolo Barella – the same height as Mpoto at 5’9 (1.75m).
