The man who designed the roof of a stadium where Madonna is to perform next week has warned the entire building could collapse during the show.

Danger: Madonna's next venue could collapse

Nodar Kancheli, who designed the canopy roof of the Luzhniki Stadium in Moscow where the pop star is playing on September 12, told the Ekho Moskvy radio station that tens of thousands of lives could be in danger if the show goes ahead.

He warned that the concert might be too loud for the building to withstand the vibrations.

He said: "The stadium could collapse if audio frequency resonates with the vibration frequency of the building. The sound waves could damage the structure."

Kancheli's past record also does not bode well for the American singer. He was the architect of the Transvaal Water Park in the Russian capital which collapsed in 2004, killing 28 people. He was found guilty of criminal negligence but this week was given an amnesty.

The Luzhniki Stadium can hold 84,745 people and is the biggest sports stadium in Russia. It was the main venue for the 1980 Summer Olympics.
