Red Bull Racing will see another frontrunner leave after this season. After Adrian Newey, sporting director Jonathan Wheatley will soon leave the Austrian team. For 18 years, the Briton worked for Max Verstappen 's racing stable, a period during which he was praised for his work by friend and foe alike. Yet Christian Horner, Red Bull Racing's team boss, does not seem all that mournful about Wheatley's impending farewell.
