Sir Dave Brailsford: UCI must be stronger on doping

Team Sky boss Sir Dave Brailsford says the International Cycling Union (UCI), must take a stronger stand against doping if the sport is to be "credible".

Astana, the team of 2014 Tour de France winner Vincenzo Nibali, retained their World Tour licence despite five riders failing drugs tests, and Brailsford says the sport's governing body must "step up their game".

Looking ahead to the new season, Brailsford says his team are "right on it" and showing the "hunger" to get Chris Froome back to the top after a disappointing 2014.
