Fixtures (Thursday, 9pm BST): South Korea vs. Belgium, Algeria vs. Russia
Belgium: Already assured of their passage, and need a point against South Korea to win the group.
Algeria: Must beat Russia to be guaranteed a place in the knockout rounds, and if they do that they could also top the group if Belgium lose to South Korea. A draw will likely also be enough due to their superior goal difference up against South Korea, as a point will send Algeria through unless South Korea beat Belgium by three goals or more.
Russia: Have to win against Algeria, and will definitely go through if South Korea do not beat Belgium. But a win might not be enough, as South Korea could overtake them on goal difference if they do win.
South Korea: Must pick up all three points against Belgium and hope other results go their way. If Algeria-Russia is a draw, then South Korea would have to win by at least three goals to go through. If Russia beat Algeria, then South Korea need to win by a greater margin than Russia to qualify. If Algeria beat Russia, then South Korea are out.
