Red Bull Racing driver Max Verstappen has opened up on the sudden ousting of his former team boss Christian Horner.

Red Bull’s Formula 1 team is changing team directors for the first time since it was founded 20 years ago, after Christian Horner's sacking sent shockwaves through the sport on Wednesday.

Horner led the team to six constructors’ titles and eight drivers’ championships, four apiece for Sebastian Vettel and Max Verstappen.
