Book - Little People, Big Dreams - Leo Messi

As a child, Leo played football passionately with his brothers and cousins in the streets of Rosario, Argentina. Aged 9, he was diagnosed with Growth Hormone Deficiency. He had to inject himself with hormones from the doctor every day to help him grow. But nothing would stop him pursuing his dream. Across 17 years he scored 672 goals for Barcelona FC and helped them win 35 trophies. And he is a hero off the pitch as a committed ambassador for UNICEF and founder of his own children's charity.
