Russia's 2010 World Cup bid chief executive Alexei Sorokin has rejected claims of collusion in the voting process.
The Russian bid beat England, Spain/Portugal and Netherlands/Belgium to win the right to host the finals in eight years' time.
England secured only two votes and were eliminated in the first round, while Russia received nine votes in the first round before going on to win an outright majority of 13 in the second round.
There were accusations of collusion between some countries and some of the 22 members of Fifa's executive members.
However, Sorokin insists there was no wrongdoing in the voting process and that everything was done in the right way.
"We never saw any evidence of collusion," Sorokin told Sky Sports News.
"The Spanish bid before the vote in their interview said they would have about seven or eight votes and it happened this way, so they were right in their assessment.
"We did not find any spirit or atmosphere of collusion.
"We are grateful to all Fifa members who supported us."
Security concernsSorokin also rejected worries over possible security concerns about the finals being staged in Russia.
"They [security concerns] will be addressed by perfect organisation of that tournament, including security measures," added Sorokin.
"We have a lot of experience in that we have hosted a lot of international events without a single security issue, without a single incident and World Cup 2018 will not be an exception. It will be very well organised."
