Toto Wolff said he "proudly" wore Red Bull colours during his own racing career as he paid tribute to Dietrich Mateschitz.
The founder and owner of the Red Bull brand died on the eve of the United States Grand Prix. He was 78 years old, and had been battling with a long illness but lived long enough to see Max Verstappen secure back-to-back drivers' titles at Suzuka two weeks ago.
Having been involved in F1 and other series for decades, Mateschitz was a popular and well-respected figure across the motorsport world. Naturally, news of his death triggered an outpouring of emotion as well as plenty of heartfelt tributes.
