Evidence of a state-sponsored scheme in Russian athletics was published by the World Anti-Doping Agency's Independent Commission in November, leading to the world's largest nation being suspended from the International Association of Athletics Federations (IAAF).

Various failures across other sports have also been recorded, including in cycling, with many assuming that similar systems exist across other sports. 

"One needs to speak about doping calmly," Mutko, who is seen as a close ally of Russian President Vladimir Putin and who also sits on the FIFA Executive Committee, told the TASS news agency.

"This is like an eternal engine, like theft, it will continue.

"People will try to make some attempts.

"All the accusations against the state and the system of Russian sports need to be simply dropped.

"There is no system, everything is phony, invented and based on false accusations and false facts."

Russian WorldTour road team Katusha face the prospect of a suspension for between 15 and 45 days after Russian rider Eduard Vorganov was provisionally suspended for a doping violation last week.

Track sprinter Yelena Brezhniva, a two-time European team sprint champion in 2013 and 2014, was also banned for four years by the Russian Anti-Doping Agency after failing a drugs test.

Mutko claimed to be more concerned with the track team rather than the road squad, and said Brezhniva acted in isolation.

"It troubles me more seriously when our rider [Yelena] Brezhniva is suspended rather than problems within [Team] Katyusha," he said.

"I fully trust all of them [the cycling team] and see no problems whatsoever."

Double London 2012 road bronze medallist Olga Zabelinskaya, Russia's only cycling medal winner at the Games, was also controversially cleared of doping by the Russian Cycling Federation last year after she failed an in-competition test for banned weight loss stimulant octopamine.

The International Cycling Union have appealed this verdict to the Court of Arbitration for Sport.

Russia's best known cyclist of recent years, Dennis Menchov. was also handed a backdated two-year ban by the UCI in 2014 due to adverse findings in his athlete biological passport. 

It has been claimed that Menchov, who won the 2007 Vuelta a España and 2009 Giro d'Italia before being sanctioned, also received blood transfusions during the 2005 Tour de France.
