Britain's David Millar has urged the sport of cycling to get its house in order following the conclusion of another scandal-hit Tour de France.
Millar finished in 69th place
This year's race has been plagued by a string of controversies, from positive doping tests to the sacking of race leader Michael Rasmussen.
"It's time for everybody to get their heads together and fix this sport," Millar told BBC Five Live.
The Scot also implored Bradley Wiggins not to turn his back on the race.
Wiggins, 27, was forced to leave the Tour prematurely when his team Cofidis pulled out after Cristian Moreni tested positive for testosterone.
"It is tragic what has happened to Bradley," said Millar.
"Bradley is collateral damage in this war against doping and if there is one person who doesn't deserve it it's Bradley Wiggins. I hope it doesn't hurt him too much.
"I can understand how terrible and resentful he feels at the moment, but I hope he comes back and rides it again."
I wanted to get a stage win but I didn't have the condition to do it
Wiggins will not race in the Tour next year as he switches his focus to the Olympics in Beijing.
But the Athens Games gold medallist has hinted he will return in 2009 despite being left disillusioned by his exit at the hands of drug cheats.
Millar finished 69th in his second Tour since completing his own two-year doping ban.
"I wanted to get a stage win but I didn't have the condition to do it," said the 30-year-old Saunier Duval rider. "I'll have to wait until next year."
