Christian Horner, the longest-tenured team principal in Formula 1, is out after two decades. Here's what he told the team.

Red Bull sacked Christian Horner, Formula One's longest-serving active team principal and one of the most successful of all time, and replaced him on Wednesday with Racing Bulls' Laurent Mekies.

Horner guided the Milton Keynes-based squad to two successful spells, yielding six constructors' titles, plus eight drivers' titles split between Sebastian Vettel and Max Verstappen.
