Thursday, June 26 will see the last fixtures of the 2014 World Cup group stages take place, as South Korea take on Belgium in a bid to secure an unlikely progression towards the round of 16.
It won't be easy: The Koreans must pick up all three points in order to have any shot at qualification. An Algeria win over Russia would rule out South Korea; a draw would require South Korea to win by at least three goals; and a Russian win would mean South Korea need to win by a greater margin than Russia.
But Hong Myung-bo's side must focus on themselves first against a Belgium side tipped by pundits and fans to be dark horses in Brazil. They haven't been firing on all cylinders just yet, but still top the group with passage to the knockout stages already secure.
Here are six key battles that will shape South Korea's clash with Belgium, and possibly who Group H sends to the round of 16.
