didn't he already release a biography?
Yes, but it's not biography at all, it's a small book, the narrative is divided into 7 parts, where he explains his ups and downs, his feelings, talking about friendship, partnership, about his parents etc., he should drop huge autobiography, but it's not right time yet
this part is from "Chapter 3. Passion" of this book (google translate):
"I can not hide the fact that my last year in " Juventus " turned out to be difficult : after twenty years of playing , it's hard to look at the field from the bench. In those moments of passion for the game covers human despondency. Let's face it : neither player believes he is worthy replacement. Each of us feels the need and desire to play . If you turn on common sense , then of course you realize that the person playing field is now in better shape and scores more than you , and therefore more worthy of a place on the field. When you stop playing on Sundays , it is automatically eliminated from the rhythm of the game. This whole situation is similar to the story about the dog , which itself tried to bite its tail . And if you have no desire to play, it is highly unlikely that the coach will make you play . What is the way out of the situation ? Think of positive things to work and work more than others. And never forget that your teammates will still remain friends and not enemies, even if there is competition for a place in the eleven players.
The captain must not forget about their duties and that he represents.
Sometimes it was not easy to enter the last quarter of an hour of play . Instead of being angry , I tried to analyze these fifteen minutes remaining . Sports teaches a lesson that we must be able to give all that you can, in spite of the time - let you stay one minute or forever . My career was , thank God, is quite long and still has not ended. I can say with certainty that the period of a career in " Juventus ", when the time I was little , allowed me to understand many things about myself . I confirmed my self-esteem and realized that passed the test . At such moments, one should approach yourself with understanding the right of self-criticism , but without excessive self-flagellation . I'm not one of whom think the president , coach or someone else , I - the one whom he represents. When the time comes , and I realize that it is time to stop, I'll be the first to admit it , but now that time has not yet come . I was born in order to understand the world around me every day , and why all this is happening. I can not always do that , but I try ."
