Christian Horner revealed details about Sebastian Vettel's early days with Red Bull as he paid tribute to the retiring Formula 1 icon.
Vettel confirmed on Thursday that this season will be his last in the sport as he plans to spend more time with family. He departs as one of F1's most successful drivers ever, with 53 race wins to his name and four world titles in as many years between 2010 and 2013.
Those championship successes came at his peak with Red Bull, where he played an integral role in transforming the team from the ambitious upstarts of the paddock to the dominant force in the sport.
