"At first we thought that the match against Iran will be played at the Spartak Stadium, but it turned out that we'll play at the training ground. We won't be able to bring our strongest [players] as the date is not official... There will be young players as well as experienced ones [at the friendly]", Jankauskas said.

Russia's first-ever FIFA World Cup will take place from June 14 to July 15 at 12 stadiums in 11 cities. The 45,000-seater Spartak Stadium will host a total of five games, including one round of 16 match.

Iran have been drawn in Group B along with one-time World Cup champions Spain, reigning European champions  Portugal and Morocco.
