FIFA has revealed there were no positive doping tests during the recent Confederations Cup in Russia.

A total of 379 tests were conducted and 854 samples taken during the tournament, the traditional World Cup warm-up event.

The worldwide governing body said they carried out 239 of the tests, with 175 of them taken out of competition and 64 in competition.

Russia were among the competing nations, along with winners Germany, Chile, New Zealand, Australia, Cameroon, Mexico and Portugal.

"FIFA set up the largest anti-doping programme ever conducted for the FIFA Confederations Cup 2017, including pre-competition and in-competition testing through blood and urine," FIFA said in a statement.

"All participating players were tested through blood and urine in unannounced controls and, additionally, two players per team were tested by FIFA anti-doping officers after each of the competition's 16 matches."

Most of the analysis was done at the World Anti-Doping Agency (WADA) accredited laboratory in Lausanne in Switzerland.

The announcement comes after Russian Deputy Prime Minister Vitaly Mutko, a former member of FIFA's ruling Council, was forced to deny suggestions the country’s national football team have been implicated in doping.

A report by the Daily Mail claimed that FIFA were investigating 34 Russian players, who were suspected of potential breaches.

It was claimed the investigation included the entire Russian squad for the 2014 FIFA World Cup in Brazil.

The FIFA investigation, which remains ongoing, reportedly stems from the McLaren Report, which claimed that more than 1,000 Russians from a number of Summer and Winter Olympic, non-Olympic and Paralympic sports had been involved in the manipulation of doping samples.

This included many cases of tampering where samples were illegally switched for fake clean ones.

FIFA President Gianni Infantino admitted earlier this month that he did not know when the probe would be completed.

Infantino also announced that all Russian players tested by FIFA at the Brazil World Cup three years ago were found to be negative.

He added that the same applied to last year's European Championships in France, where UEFA were in charge of testing.

The Confederations Cup ran between June 17 and July 2.
