Motorsport: Impossible to say Hamilton is the F1 GOAT - Stewart

Three-time F1 World Champion Jackie Stewart says you just can't resolve the greatest of all-time debate. Jackie: "A fantastic achievement to win as many races as he has. He’s driving definitely the best car on the track. Nevertheless, he’s driven extremely well but it’s very difficult to say he was the greatest driver of all time. Was Fangio better than Michael Schumacher? You don’t know that. But Lewis has driven extremely well and deserves the success that he's had."
