The 2018 World Cup could be the most expensive in history, with Russian business news outlet RBK putting the total spend on the tournament at close to $14 billion (£10.6bn).
Russia has increased its government subsidies for the World Cup by $13 million amid concerns over the legacy of the tournament.
Two government orders allocate an extra $7.6m for temporary World Cup infrastructure and $5.3m to the state company responsible for maintaining the stadiums.
That takes total spending on the World Cup to around $10.7bn, although that figure does not include some key spending on infrastructure.
Several Russian regional officials have asked for more federal spending after the World Cup to stop the stadiums losing millions of dollars a year.
The venues are expensive to maintain and often several times larger than the average crowd for Russian league games.
