Matches with full knowledge of what each team needs or doesn't need to advance to the next stage. Saudi Arabia just wants to win without caring what will happen in the match between Poland and Argentina. It also passes with a draw, if Argentina loses. As far as Mexico is concerned, qualification goes through combinations that are not very likely. In addition to his own victory, he needs a defeat of Argentina, or a defeat of Poland while covering the goal difference with Poland (-4) or a draw in Poland-Argentina and covering the goal difference with Argentina (-3). Simply put, qualification for Mexico is not that much of a possibility even if they win. I will bet on the Saudis who showed positive elements in both the previous games.
