This is Nigerian footballer Sekou. The book in his hand translates from Russian to 'Black Monkey'. He's holding it because he was asked to by his teammate Sergey Ignashevich, who took the photo it to the web.
why does Sergey Ignashevich own a book called Black Monkey?
how does a 33-year-old still find something like this funny?
Thanks to Artur Petrosyan of Sportbox.ru who let the non-Russian speaking world know about this via his Twitter account.
