Heavy rain damaged one of Russia's newly-built World Cup stadiums on Sunday when the tournament ended with the final in Moscow.
Footage from the southern city of Volgograd showed a fresh landslide on an embankment near the stadium, which made a several-metre-deep hole in it and fully covered a sidewalk with mud.
A spokesman for the state Sport In company overseeing the construction said there were also leaks inside the stadium which could take up to a week to repair.
Volgograd Arena, a stadium that can accommodate up to 45,000 spectators, was built for the World Cup at a cost over 16bn roubles ($257mn), according to data on the regional government's website.
Eight teams played World Cup group matches in Volgograd, including England and Japan who made it to the knockout stages.
Spokesmen for the Volgograd government and Sport In said the rain was extraordinary and was dealt with as an emergency.
"This happens once in a hundred years," a Sport In spokesman said.
The Stroytransgaz company, which built the stadium, gave no immediate comments.
