All of the 12 Russian stadiums due to host matches during the 2018 FIFA World Cup have now been commissioned.
The Samara Arena was the last to be opened with a test event held there at the weekend.
Construction delays on the project mean minor work still needs to be completed on the venue, however, before the World Cup begins.
General Director of the 2018Local Organising Committee (LOC) Alexei Sorokinsaid:
At least three test matches have been scheduled to be held at each commissioned stadium. We are now focused on the operational and not the construction aspect.
We are not expecting surprises from FIFA and the organization will be definitely satisfied that all stadiums were granted certificates of compliance with the required technical norms.
Half a million foreign tourists expected in Russia for the 2018 FIFA World Cup which kicks off on June 14 in Moscow.
