In five previous appearances, Saudi Arabia have qualified for the round of 16 only once, on their debut at the tournament in 1994.
In Qatar, Poland lead Group C on four points, one ahead of Argentina and Saudi Arabia, while Mexico are on one point.
If the Saudis want to progress, they will have to beat Mexico, regardless of the outcome of the match between Poland and Argentina.
Herve Renard’s men stunned the football world when they defeated Argentina 2-1 in their opening group game, only to lose 2-0 to Poland in their second match.
Said Renard: “No one around the world thought that we could play with this level. Yes, in Saudi Arabia, we know the players well but they are unknown to the fans around the world. We are still alive.”
As in the first two matches, the Saudis will be supported by thousands of fans.
