South America is one of the hotbeds of football, and in this series we explore the different countries of the continent. In each episode of The South America Files, we'll be looking at how the game has developed; the clubs, the players, the joys and despairs. Guided by our South American football expert Dr Pete Watson, this time, we're off to Ecuador, who have never finished higher than fourth in the Copa América, but produced the best goalscorer in Copa Libertadores history.
