F1 has long been raged with a debate over who the greatest driver in history is and that is something which will continue to happen for as long as the series exists.
Statistically, it is Lewis Hamilton, but there is also Michael Schumacher, Ayrton Senna and even Max Verstappen coming into the fold. This is not to discount Jim Clark, Juan Manuel Fangio, Stirling Moss et al, but is more a reflection on the ever-increasing length of seasons and careers.
However, none of those drivers would have been able to achieve what they did without a great team and leader behind them.
Hamilton won six of his championships under the leadership of Toto Wolff, Jean Todt led Schumacher to five titles, while Christian Horner took seven titles between Sebastian Vettel and Verstappen.
So, F1 is lucky enough to have been graced with some great leaders over the years but, statistically, who is the best?
