Form has dipped on track following the departure of technical supremo Adrian Newey, and a very public spat between Horner and Jos Verstappen, father of four-time world champion Max, has played out for all to see.

Huge news came out of Formula 1 on Wednesday as Red Bull Racing announced it had fired team principal Christian Horner after 20 years and 14 championships. Max Verstappen has become the best F1 driver in recent years, winning the last four drivers' titles, all with Horner in charge.
