In the past, it has been easy to downplay Jenson Button's results. He was outclassed by or did not dominate various team mates in his early career, before finding himself down and out after multiple lacklustre seasons at the likes of Benetton and Honda. There was a multitude of unfilled promise that looked to never be ended.
Even his title-winning season at Brawn did not change many people's opinions of the Englishman. His second half season performance at Brawn showed us still that in a car that wasn't light years ahead of the rest, he struggled.
Most, if not all, therefore expected him to be destroyed by Lewis Hamilton at McLaren. Last season, however he appeared to be a lot closer to Lewis than we predicted. And this season, he emerged at the triumphant number one at the team.
For me, the turning point actually dates back to the Brazilian Grand Prix of 2009 whilst he was at Brawn.
This was where we caught a glimpse of the previously unseen fight and determination that Jenson had within him. He bulldozed his way into third position, claiming the drivers title as a result.
The knock on effect was echoed in Canada this year where he pummelled his way from last to first in an awe inspiring comeback to rival the best sporting comebacks of all time.
Not only has his overtaking ability improved, his consistency in pace has also come on leaps and bounds. No longer is he a driver unable to chase a victory with consecutively flawless laps. Victories in Hungary and more so his triumph in Japan highlighted that he didn't require mixed weather conditions to come out on top.
He showed that in normal racing conditions that he could dominate from start to finish in a car that was not visibly stronger than all others.
After this season he is a more mature and intimidating opponent, causing all of his rivals to take note. Lewis Hamilton now knows more than most, that Jenson is not to be underestimated.
