The final match of the first round of World Cup group games takes place on Tuesday evening in Cuiaba as Russia take on South Korea in Group H.
Russia are led by former England manager Fabio Capello and are the current favourites of the remaining three teams to join top-seed Belgium in the knockout stage.
They come into the tournament in solid form, with their last defeat coming almost a year ago against Northern Ireland in a qualifier.
Hong Myung-Bo's South Korea side, meanwhile, enter the finals in poor form having lost four of their last five international friendlies and failing to score in each of those defeats.
Capello is without key midfielder and captain Roman Shirokov, who was ruled out of the tournament just over a week ago.
Shirokov's absence could mean more of an emphasis on the wide areas for Russia, with former Chelsea man Yuri Zhirkov potentially key.
Up front, young striker Aleksandr Kokorin could get the nod ahead of the more experienced Aleksandr Kerzhakov.
Hong has a tough choice on who to start in attack with Park Chu-Young and Kim Shin-Wook vying to lead the line.
These two recently met in a friendly last November, with Russia coming from behind to win 2-1 in Dubai.
Though the names don't inspire much historical excitement in the international soccer realm, the match between South Korea and Russia Tuesday could determine which team joins Belgium in the knockout round from Group H.
Aside from those three, Algeria will be battling to make it through.
Both sides have had issues leading up to the Cup. For Russia, it's the injury to star midfielder Roman Shirokov, who was lost to a back injury. For South Korea it has been mostly subpar play. They lost to this Russia team in a friendly back in November and were smoked by Ghana 4-0 in Miami.
