Cristiano Ronaldo has revealed what he thinks is the “most important tool” behind his longevity after plying his trade across Europe and now in Saudi Arabia. The Portuguese icon is showing no signs of slowing down, even at 40, as he continues to chase down records with Al-Nassr and on the international stage. He has set himself the mind-boggling target of reaching 1,000 career goals before hanging up his boots, and he is just 51 short of reaching that total.
