Many Real Madrid fans deem it the most important Champions League victory for the club. After years of futility, having been stuck on 9 titles for what seemed like eternity, the La Decima finally came after more than a decade. It would open the door to 3 more Champions League titles in the next 4 years.
Just like it was for Real Madrid, the number 10 is significant in many ways. After all, most people have 10 fingers and 10 toes, and 10 is the base of the decimal numeral system we use. Pythagoras, yes, the one with the theorem, thought that 10 the most sacred number of all, because 1 + 2 + 3 + 4 = 10. The numbers represent the following: (1) existence, (2) creation, (3) life and (4) the elements earth, air, fire and water. Just in case we forgot, the Bible has 10 commandments. Finally, 10 is the first number with 2 digits in the decimal numeral system.
All this is to say that la decima is worth pursuing, for it shows that you have repeated the process for at least 10 times. Now it is on to the next 10.
