Sergio “Kun” Agüero rose to fame as one of Argentina’s greatest footballers – a best friend to Messi, the son-in-law of Maradona, record-breaking goal-scorer and an unexpected legend in England – from the most abject poverty. It’s an archetypal story of rags to riches, but told with searing honesty, including his clashes with his overbearing father, fear over his heart condition, desperate loneliness as a teenager, his conflicts with managers, and his emotional journey of becoming a father. His life is shaped by turning points and revelations, and what shines through is his humour, and creativity. This is the story of a boy who has lived and learnt fast, told by Kun himself, his family and other footballing legends like Messi and Guardiola.
