Even if there have been several doping cases in recent days, Russia's sports minister Vitaly Mutko explains that je has full confidence in his system.

"I fully trust the athletes and trainers," he told to news agency TASS on Monday. "I don’t see problems of any kind here."

RUSADA, Russia's anti-doping agency, announced last week that track cyclist Yelena Brezhniva has received a four-year suspension for doping. A few days ago, Katusha rider Eduard Vorganov, a former Russian road race champion, was provisionally suspended. He tested positive for meldonium, a banned substance.
