Roughly translated, it reads...
- Remove the official Getafe C.F. t-shirt from your Burger King bag.
- Wear your t-shirt when you feel like a star.
- Shoot, and make a goal.
- Prepare to celebrate.
- Show everyone that you have the King inside.
Also, I'm left to wonder if the text really is for the people getting the shirts, or was it written so that the marketing agency who created the instructions could charge Burger King more money because they "had" to get their copyrighters and editors to work on it?
