Notes
--This can be completed on the "Amateur" difficulty
--Selecting Canada or Trinidad & Tobago will allow you to also unlock "Second Trip, First Goal." You must set the difficulty to at least "Semi-Pro" for this particular achievement, which can be done before you start the match. Personally, I completed the World Cup (on Amateur) and then reloaded the final match on "Semi-Pro" and scored a goal to unlock the achievement.
--This CANNOT be completed in "Captain Your Country"-- Thank you to QueensOwnRifle for the clarification.
--Thank you DarthFracas for the clarification about the playoff fixture.
