What is the fewest number of countries needed to manufacture a soccer ball and a pair of shin guards?

The fewest number of countries needed to manufacture a soccer ball and a pair of shin guards can be as low as two. For instance, one country could produce the soccer ball while Another Country manufactures the shin guards. However, if materials for both products are sourced from a single country, it may be possible to produce both items there, reducing the total to just one country.
