This reviewer seems a bit critical of David Beckham
"It has been many years since this guy stopped worrying about playing soccer, and focused solely in his obligations with sponsors, in posing for photos, etc. He has won absolutely nothing in Real Madrid, a team so engulfed by its millionaire stars that no coach can make it work as an efficient soccer team.
It's useless to read a book about this narcisist (sic) guy."
Soccerhead is the best soccer book I have read. Anson Dorrance says it is the best book written on soccer. If you like soccer, you need to read it. I found a website for it:
