Andrew Jennings once wrote a very interesting book about FIFA called "Foul! The Secret World of Fifa: Bribes, Vote Rigging and Ticket Scandals" - That was around 2008. Since then, Jennings' journalism has deteriorated severely, from his Panorama TV shows where he ran around shouting across car parks like a crazyman, to this rather childishly written book. Jennings has become far too close and personal to the subject matter, meaning he is no longer able to cover it in an intelligent and measured manner.
He has effectively morphed into Carrie (Claire Danes) in the Homeland TV series. His heart might be in the right place, and more often than not he's probably on to something, but his now frantic, slightly crazy, and far too personal approach means that you can't take him seriously enough.
Moving away from the author, and to this book specifically, there are some very interesting parts, and he's dug up a lot of rather embarrassing and shocking details on the various men involved at the top of FIFA and the IOC, as he has done throughout his career. Unfortunately though, you have to wade through paragraphs of juvenile insults, nicknames and plain nonsense. Constantly referring to Chuck Blazer as "The Belly" for example. Far too much time is spent covering utterly irrelevant information and bits of gossip. I found myself actually getting irritated by some of what I had to read.
In many respects Jennings is a very good investigative journalist. He has a canny knack for getting his hands on secret documents, and most of his success has been on the basis of this. On the other hand, in this book there's too much weight given to the "this guy told me this once" kind of source. The occasional little anecdote is fine, but they're effectively irrelevant, and they come up rather too often, in particular in relation to already irrelevant bits of gossip.
On top of that the standard of writing is surprisingly low, which in addition to the above means that you would be forgiven for thinking that you were reading a print out from an amateur blogger. In fact it wouldn't surprise me if Jennings had lifted some of the chapters straight from his blog.
All in all, it's ok, but I would expect better from an experienced journalist.
