An F1 insider has opened up about an alleged heated argument between Christian Horner and Max Verstappen's father.

Horner leaves Red Bull with eight Drivers' Championship and six Constructors' Championship trophies under his belt, having overseen one of the greatest dynasties in modern F1 history in the ground effect era. His replacement, Laurent Mekies, has an unenviable task on his hands.

Red Bull has lost several key figures across the past 18 months, most notably design legend Adrian Newey, Sporting Director Jonathan Wheatley, and Chief Designer Rob Marshall. The sacking of Horner means that a fourth pillar of long-term success is gone.
