Red Bull has pledged not give up on the Formula 1 title fight until it's mathematically impossible for Max Verstappen to win, even after Christian Horner was fired as team principal.

All speculation about Max Verstappen's move to Mercedes may well be nonsense, according to Juan Pablo Montoya. The former F1 driver seriously considers that George Russell has already signed a new contract with the German team.

Frenchman Laurent Mekies got down to work as Red Bull team principal on Thursday, a day after replacing Christian Horner, and recognised big challenges ahead for the once-dominant former champions.

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.

With Christian Horner's departure, a wish from the Max Verstappen camp has been granted, but is it wise to stay? Horner's dismissal actually suggests that Verstappen should leave. In recent weeks, GPblog learned that Christian Horner's departure was a significant point for Verstappen's camp.
