The Italian coach, who is under contract until 2018, has come in for heavy criticism after Russia bowed out at the group stage in Brazil, having been pipped to second place in Group H by Algeria.
Some members of the Russian parliament even called for Capello to be dismissed but Nikolai Tolstikh is standing by his man.
"In September our team will participate in qualification for the  European Championship, without forgetting preparations for our home World Cup [in 2018]," the RFU president stated.
"The criticism and analysis is normal, but we need to focus on the improvement of the play of our team, so we need to be constructive.
"When we talk about the length of Capello’s contract, there are no termination clauses. Now we need to talk about something else."
