F1 title win for unlucky Lewis Hamilton would be his greatest, says Jenson Button

Formula One - Japanese Grand Prix - Suzuka Circuit, Japan

Jenson Button views the Formula One title race with the wistful gaze of the non-contender. He is in 15th place with 19 points, 269 behind the leader, Nico Rosberg. He was a champion once, in 2009, and with 300 races behind him his opinion is meaningful as Rosberg and Lewis Hamilton do battle over the final races of the season, starting with Sunday’s Japanese Grand Prix.
