Mercedes boss Toto Wolff believes Sebastian Vettel would have won the U.S. Grand Prix had he not collided with Red Bull's Daniel Ricciardo on the opening lap.
Vettel was sent into a spin after hitting Ricciardo as they battle for fourth place. The Ferrari driver was able to recover to finish fourth, overtaking Valtteri Bottas on the penultimate lap, to keep his very slim title hopes alive.
