It shows you how much mental fortitude it takes to perform at the highest level. Messi, Ronaldo and now Salah have the skill and the mental attributes but it takes a whole different person to take care of your body to perform at that level.

Neymar is probably the most skilled out of them all but the work ethic is closer to Ronaldinho. He could’ve been a beast if he cared more about his legacy like Messi did.
