Aston Martin team boss Mike Krack has put the blame for Sebastian Vettel and Mick Schumacher’s Miami crash firmly on the shoulders of the Haas driver.

Racing for points at the Miami International Autodrome, Vettel overtook his young mentee only for Schumacher to fight back almost immediately.

The Haas driver tried to retake the position up the inside of Vettel, but instead made contact.

Vettel retired as a result while Schumacher lost out on his first F1 World Championship points as he had to pit for a new nose cone, finishing last of the classified runners.

Krack believes the 24-year-old has only himself to blame.
