When he was just six years old Nico Rosberg decided he was going to emulate his famous father and become a Formula One World Champion. It seemed a far-fetched fantasy, even for a boy benefitting from a privileged upbringing in Monaco. Indeed it took 25 years of hard effort for Nico to make his childhood dream come true. His championship quest took a heavy toll, prompting a final twist in the tale of triumph. Five days after taking the title, in a dramatic last-race showdown with his team mate Lewis Hamilton, the 2016 World Champion announced his immediate retirement from the pinnacle of motorsport.
