Formula 1 supremo Bernie Ecclestone has paid tribute to world champion Lewis Hamilton, describing the Mercedes man as "outstanding".
The Briton took his second drivers' title in 2014, beating Nico Rosberg by 67 points in the overall standings.
Ecclestone believes that Hamilton is comparable to some of F1's all-time greats.
He is quoted by The Express as saying: "As a driver, he is absolutely outstanding, as good as there has ever been.
"Apart from the fact he's talented, he's a good guy, he gets out on the street and supports and promotes Formula 1. He's 100% box office."
Hamilton won the season-opening Australian Grand Prix ahead of teammate Rosberg.
