Despite being only 51, Christian Horner is the longest-serving team boss in Formula 1. It has been 20 years to the day at Red Bull Racing, taking charge of the Austrian team on January 7, 2005. The Briton has seen many colleagues come and go, with Oliver Oakes being the latest new face among team bosses. Horner knows better than anyone how Oakes must have felt in the early days at Alpine.
