Query: Please stay out of the field...!!!

This book is a bigotry masqueraded behind the veil of a "scholarly work." Every rule of rigorous work has been violated in this piece of work building on the darkest but forever smallest side of "soccer." Wasting this great opportunity to reveal the multi-dimensional power of the game the author invests his bitterness against the sport page-after-page. A sweet revenge for "soccer" rejecting him in his early age? Well... my advise to the author... keep on running away from the ball sir... and please stay away from it!!! You are RUINING THE GAME!!!
