Christian Horner was visibly emotional as he reacted to the death of his long-time boss, Red Bull owner Dietrich Mateschitz.
The Austrian billionaire died on Saturday at the age of 78 after a long illness. Red Bull staff were informed of the news shortly before it was made public, as Sky Sports TV cameras spotted a crowd of employees emerging from a meeting in the team hospitality area in the Austin paddock with sombre faces.
Shortly after, Horner spoke to the broadcaster to pay tribute to a giant figure in Formula 1 and motorsport as a whole. "It's very, very sad," he said. "What a great man – he's few of a kind, what he achieved and what he's done for so many people around the world and across different sports is second to none.
