Thomas Gravesen was one of the last footballing mavericks, once dubbed 'a grenade with the pin pulled out'. Hailing from rural Denmark, he fulfilled his childhood dream of becoming a top player but never lost his unique identity, earning a reputation for his bizarre antics and eyebrow—raising behaviour. Gravesen lined up for Real Madrid's glamorous Galacticos and enjoyed colourful spells at European giants Hamburg, Everton and Celtic. Remembered as a cult hero at all of his past clubs, he is a truly fascinating individual. After abruptly ending his career and disappearing, he re—emerged years later in bizarre circumstances in Las Vegas. Did he really lose $54 million at cards? Did he really bring dynamite to training, and spend his summers in a dark basement? Known as a 'unicorn' due to his mysterious life, this is a fascinating, helter—skelter journey into the mind of 'Mad Dog'. Team—mates, coaches and friends recount what it was like to be swept up in the surreal whirlwind of the most unorthodox individual they've ever encountered.
