A former Red Bull driver has claimed that Max Verstappen has another contract clause that would allow him to leave the team ahead of next season. The reigning world champion looks set to be denied a fifth straight Drivers' Championship title with McLaren much quicker than any of their rivals.

After a “home race to forget” for Red Bull, Helmut Marko concluded that another title with Max Verstappen is very unlikely this year. But just how serious are the team’s issues?

As reported by GP Blog, the Dutchman intends to stay at Red Bull for the next season despite the uncertainties surrounding the new powertrain project in collaboration with Ford and within the team, but things could still change quickly.
