I was surprised to get interested in tennis matches descriptions, I who love this sport very moderately.
What I liked is the description of the game from the inside Agassi: feeling depressed after a failed ball, then the return of confidence, doubt, the state of grace, turning situation following the rain to stop ...
And this amazing thing Agassi did not like tennis! He played his last game with cortisone injections and ended in a pitiful physical state.
There was also the "people" with all the people he met, all these famous people but very annoying!
