The hosts, who knocked out 2010 World Cup winners Spain from the World Cup in the round of 16 to reach their first-ever World Cup quarter-final since the end of the Soviet era, will next face Croatia in Sochi on SUnday (4am AEST).

"We will not stop here, we have more things to accomplish. We want to go as far as we can. I would even say that the more you get, the more you want. So every time you want more and more," Kutepov said.

The 24-year-old defender added that the match against Croatia would be tough but the players still wanted to progress into the semi-finals.

"When we were playing in the group-stage we thought it was good to get the first win, then the second too, and we achieved our one goal of progressing. Then we started to want more and more. Spain would be tough but we wanted to go further. We beat Spain. Croatia will be tough, but again we want to go further," he added.

The 2018 FIFA World Cup kicked off on June 14 and will continue until July 15, with the final set to be held at Moscow's Luzhniki Stadium.
