Russia reached the quarter-finals for the first time since the break-up of the Soviet Union where they lost to Croatia 4-3 on penalties in Sochi on Saturday after the match finished 2-2 following extra time.

"We are killed, upset, broken, but very proud. We don't give up. This is the first time in a while that we are proud of each other. We are very happy that, maybe not perfectly, but we managed to show our best qualities and become one team, one unity," Dzyuba said in a video interview posted on the Russian Football Union YouTube channel.

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