Button faces another huge challenge

LONDON: Jenson Button faces the toughest challenge of his Formula One career when he joins Lewis Hamilton at McLaren next season and he knows it.

"Life is all about challenges and, most important of all, it's about challenging yourself," the 29-year-old world champion said after the Woking team announced he had signed a multi-year deal on Wednesday.

"Although I won the World Championship with Brawn GP last year, and I'll never forget that, I was always adamant that I wanted to continue to set myself fresh challenges."
