First of all Ecuador isn't really all that good, as one thing is to play flowing attacking football against Costa Rica, another is to play against England or Germany. Of course, you could argue that England is playing pretty badly but for all its faults the English team has a defensive solidity that the Costa Ricans can only dream of. Furthermore even if Ecuador is as a good a team as you say, there are numerous examples of good teams that just choke up when the going gets tougher. Ecuador wouldn't be the first, and they certainly won't be the last.
Anyway, while corruption is, unfortunately, a big part of football, to think that the English FA bought up the whole world just to win the World Cup is crazy.
