- Longevity: The players making our list have been talismanic players for club and country. I use total games played as a sign of longevity.
- Trophies: This is tricky. However, when we need to decide between different options, it is best to use simple, absolute and brutal differentiation. For this reason, I’ve limited it to International Trophies — World Cup, European Championship and Copa America. The bar is set high because we’re talking about the best of the best at the world stage.
- Goals: The total number of goals scored in all competitions. There is an argument that this metric will exclude traditionally non-scoring players. But, when all is said and done, football is about scoring goals. Goals win games. Players who score goals to win games become legendary.
