The Russian Football Union has been urged to disclose new coach Fabio Capello's contract details by a politician.
MP Igor Lebedev has accused the union of overspending its budget, with ex-England coach Capello's appointment in July believed to have been at much expense.
"The disproportion between spending on hiring several foreign coaches for the national team and the money spent on the development of mass soccer in Russia is quite obvious," Reuters reported Lebvedev as saying.
Former RFU chief Sergei Fursenko, regarded as a close friend of Russian President Vladimir Putin, hired former coach Dick Advocaat but quit his role in the wake of the country's elimination at the group stage of this year's European Championship.
Current RFU chief Nikita Simonyan advised Lebedev he should contact "Mr Fursenko directly instead of making requests to us".
Whereas Advocaat was reportedly paid €7.5m a year, Capello is apparently on an annual salary of $12.4m even though the RFU face a deficit of up to $30m.
Capello oversaw England's qualification to the 2010 World Cup and this year's Euros, but departed as coach in February 2012 after disagreeing with the Football Association's decision to strip John Terry of the captaincy.
The 2010 World Cup campaign was fraught with disenchantment at the 66-year-old's autocratic style in South Africa, before ending in a humiliating round-of-16 4-1 defeat to Germany.
