No Irish sportsperson has had more written and said about him. None has had more of substance to say for himself. Across nearly four tumultuous decades, from callow teen prospect to grey bearded influencer, Roy Keane has transcended sport, redefined the parameters of fame, and captivated the nation. Our hopes, dreams and sometimes our despair have been wrapped up in him, his exploits and outbursts. Oscillating between national treasure and national argument, he put the manic in talismanic, bestriding Lansdowne Road one minute, getting booed there the next.If the sporting heroes of every era offer a window into a society, We Need to Talk About Roy is a fascinating portrait of who and what we were in the age of Keane, showcasing our vices and virtues, our fortunes and foibles. The best of us, the worst of us. He is of Ireland and Ireland is of him.
