Swiss judicial authorities are probing the awarding of the 2018 and 2022 World Cups to Russia and Qatar as part of a far-reaching corruption scandal that has also raised questions about the 2010 event in South Africa.
"We fought in an honest manner (for the tournament) and we won. We do not think the decision should be questioned," Putin told journalists on the sidelines of an investment forum in Saint Petersburg.
"We were ready, and that's what convinced FIFA. The stadium construction has already started," he added.
Putin said that Russia supported the corruption probe currently unfolding at world football's governing body, but said it was "up to a court to decide if someone was guilty".
The president said an inquiry had already been opened into the bidding process in Russia but no evidence had been found of any corruption.
