This book is admirable for its erudition and its focus on the evolution of tactics from the playing fields of nineteenth century public schools to the present. One really must admire a British specialist who digs into the entire global picture of football and comes up with a relatively comprehensible narrative out of what must have been reams of club histories and match reports that probably contain very little of the information the author seeks. It is readable, informative and occasionally funny. Here comes the "but". Quality really declines toward the end, as if the author was rushing to meet a publishing deadline or simply outsourced the job to a football fan with a bizarre form of Tourrette's that forces him to spout senseless combinations of numbers such as "3-3-3-1, 4-5-1, 3-4-1-2". The next-to-last chapter is completely unreadable. Whereas other chapters developed the story of a single innovator or the situation in a single country, this one just rushed through a myriad of modern formations and discusses sweeping issues such as the disappearance of the playmaker. Another late chapter devotes incomprehensible amounts of space to an obscure polemic between a football statistician and a future England coach. The central narrative is lost completely, which is tied to another central weakness: the lack of occasional paragraphs to sum up the evolution of tactics as the long procession of teams, coaches and players parade through the foreground of the book and just as quickly disappear from view. The title "Inverting the Pyramid" is a brilliant example of this: it sums up an immense amount of information into a neat little compact literary phrase, but that kind of brilliance is somewhat absent from the rest of the book. In short, I enjoyed the book, I learned a lot from it and I will probably return to it frequently after matches, but it really could have used a little more tidying up from an editor (hopefully in a future edition).
