"The Russian people played a magnificent role in making people feel welcome. There were no issues to report on Russians inside stadiums. We hope that this World Cup will have a long-term impact on Russian society," Powar said.

He added that some 50 representatives of the organization had worked at the stadiums and their experience "has been largely positive."

"The Russian state together with the Russian Football Union did quite a lot of work in terms of ruling off individuals that there were concerns about. A number of individuals were denied their FAN IDs. All this combined led to quite a good tournament," Powar said.
