Hamilton's best yet to come - Mansell

Former Formula 1 world champion Nigel Mansell says the best is still to come from Mercedes driver Lewis Hamilton.

Hamilton overtook team-mate and world title rival Nico Rosberg to win the US Grand Prix on Sunday and extend his championship lead over the German to 24 points with just two races remaining.

Mansell, who won the world title in 1992, believes Hamilton is "getting better and better" and has shown he has the upper hand in his battle with Rosberg.
