Christian Horner is extremely proud of the performance of Max Verstappen and the Red Bull Racing team. For Verstappen it was the first time he had achieved a grand slam and for Red Bull it was the first in the hybrid era.
Horner proud
"He enjoyed his stay in Austria. It's fantastic that he took two wins. I'm proud of the work he did today. It's great for the championship," Horner said to the Ziggo Sport cameras.
"It's the first time for him, it's the first time in the hybrid era," Horner continued about Verstappen's grand slam. "For us it's now five races in a row that we've won. A phenomenal performance from the team. I'm proud of everything they do. But we have to keep going, we're not even halfway there yet."
