Russia will face Croatia in the quarter-finals in Sochi on Saturday.

"Russia are doing very good. The fans are the real 12th player. We can only wish them [Russia] good luck. After such a result [you] start to believe that Russia can reach the final. You look at this unpredictable World Cup and understand that anything is possible," Kombarov said. 

Kombarov was included in the extended Russia squad but did not make it to the final 23-man squad eventually.
