Better dope testing 'gave me a chance', says Nibali
Italian rider says improvements in policing created a level playing field, allowing him to stamp his class and win this year's Tour de France

Vincenzo Nibali said he would never have been in with a chance of winning the Tour de France had it not been for recent improvements in tackling doping.
The 29-year-old Italian is widely regarded as a clean rider and his victory on Sunday in this year's Tour was seen as proof that cyclists can win without resorting to cheating.
The reaction to his success is a far cry from that which greeted Lance Armstrong's seven successive wins during the darkest days of blood doping and use of the banned substance Erythropoietin (EPO).
What makes the Tour so much bigger is the international attention it demands. It's bigger, it's more beautiful
When Armstrong won his first Tour - he has since been stripped of all seven - there was no test for EPO while throughout his reign testers were struggling to keep up with the cheats.
But now with random out-of-competition tests and the biological passport, cycling has come a long way.
"Steps have been taken and great progress has been made and with it my results have arrived," said Nibali.
"I have to thank [doping controllers] because without these iron controls maybe I wouldn't be here today."
The final stage was a traditional procession that culminated on the Champs Elysees. Nibali has now joined a select group of six riders to have won all three Grand Tours - after the Vuelta a Espana in 2010 and Giro d'Italia in 2013.
