Sorokin said the Russian team's unexpected success at the tournament had been a contributing factor to the World Cup's appeal.
"It's good that our team remains in the competition," he said of the hosts, who entered the tournament as the lowest-ranked team. "There is a lot of interest."
Russia will face either Croatia or Denmark in Sochi on Saturday in the quarter-finals. The two sides were tied 1-1 after 90 minutes of their round-of-16 match on Sunday and going into extra time.
