Jenson Button needs at most six points to clinch the Formula One title in Brazil this weekend and become Britain’s 10th world champion.
If he does wrap it up at Interlagos, a debate that has been going on for some weeks now will only pick up speed — just how does the 29-year-old rate as a champion compared to all the others?
There are some who hold the view that Button will somehow not be a truly worthy champion, their opinions influenced by the Brawn driver’s inability to assert himself in the latter part of the season.
Some might argue that champions like Michael Schumacher, Ayrton Senna or Lewis Hamilton made their greatness evident from the moment they arrived in the sport.
