Let's turn our focus to the Korean squad. They don't exactly have the wind at their backs entering these games, having lost their recent friendlies in uninspiring fashion.
That's right. They lost their friendly at home against Tunisia, 1-nil -- and then fell 4-nil in Miami against Ghana in their last rehearsal before the World Cup.
Let's first look back to Korea's performances in past World Cups.
Of course they presented us with the miracle of finishing fourth at the World Cup held at home back in 2002 -- but they haven't been so brilliant in other games.
In Brazil 2014, their first match against Russia will be pivotal, to boost the team's confidence and to earn game points ahead of Belgium and Algeria.
Taking a look at their lineup from the latest game -- Arsenal forward Park Chu-young must now prove that he could score as a one-top striker. But more people are anticipating that the "Son-sational" Son Heung-min, playing in the Bundesliga, could be the game changer -- as well as midfielder Ki Sung-yueng of the English Premier League's Swansea City.
