The World Cup—which gets underway on Thursday—is a breeding ground for an underground, nefarious realm known simply as "the transfer market."
Each club around the planet will be scouting, taking notes and appraising international stars they hope to acquire once the tournament reaches its conclusion. Previously unknown names, or known underachieving ones will be given the globe's largest talent showcase to display their abilities as they become a commodity.
If you are an established name, your stock can only be hurt. Dressing-room secrets will not be kept, play on the pitch will be scrutinised to untold levels and conduct off the pitch likewise.
As every man is now a reporter of sorts—nothing will remain hidden. All of the best players know this, and they are in Brazil with the express purpose of achieving glory for their nation, representing their families and making sure no stone in their quest for greatness is left unturned.
The summer transfer window has a way of making clubs spend irrationally, after a World Cup—the values of players tend to rise. Each player has value, whether their price tag goes up or down depends on many factors but the most important is effort.
With all that said: Who are each nation's most valuable players? Who has the most to lose and who will go about giving themselves, and their nation, a positive account come the end of July?
Glad you asked...
