Red Bull team principal Christian Horner isn’t ruling out the possibility of Max Verstappen leaving Formula 1 before his contract expires. The Red Bull team boss believes Verstappen’s strong-willed nature could push him to walk away from the sport if he no longer finds it enjoyable. The Dutchman has previously criticised the 24-race calendar in Formula 1 and may prefer to drive somewhere with a less strenuous calendar. For now, he remains fully focused on succeeding with Red Bull.
