Froome wants to prove people wrong

Chris Froome says the desire to prove his doubters wrong is the primary motivating factor in his quest to become the first man to win back-to-back Tour de France titles since Lance Armstrong was stripped of his seven race wins last year.
Froome has come to terms with the fact there will always be those who question his success and that of his Team Sky team-mate Sir Bradley Wiggins, but is determined to show his sport’s darkest, drug-tainted days are over by establishing a new era of dominance.
