The head of Russia's successful campaign to host the 2018 World Cup finals has again insisted there was no wrongdoing in its bid.
Swiss authorities have seized files and financial documents as part of an investigation into the bidding process for both the 2018 event and the 2022 finals in Qatar.
A FIFA report in the process, produced by lawyer Michael Garcia, was hampered after the computers used by the Russian team went missing -- meaning crucial evidence on its bid could not be examined.
Alexei Sorokin told Sky Sports News: "We have repeatedly stated that we're not afraid of any investigation.
"We cooperated with the investigation that was going on for about two years which was headed by Mr [Michael] Garcia. We submitted all the facts, all the papers, we submitted our testimonies -- we did everything the process wanted us to do. We don't know what else we can contribute to that.
"We repeatedly said the process was transparent and that we're not concerned with any investigations. It's just strange there's a chance to go through the same thing again, where everything was seemingly closed."
Asked if he was worried about a re-vote, he added: "No, because we are so deep in the preparation, we've done so much. Our government, our country, has done so much already for the preparation of an excellent World Cup, I don't even want to discuss it with anyone."
On the missing computers, he said: "It's the honest truth. I can't change the past. It was leant to us and then taken back. Computers are not antique cars - they don't last forever.
On Blatter's future, he insisted: "We wish the current president all the success in the elections."
