The Spartak Moscow midfielder believes his side can expect a difficult match as the Blaugrana have some of the finest talent on the planet on their books
The Russian powerhouse were beaten 3-2 at Camp Nou earlier this Champions League campaign, and will be gunning for revenge when both teams meet again this week.
"Barcelona have not really changed much since Tito Vilanova has taken over. They still have the best players in the world and it will be very difficult to beat them," he was quoted as saying by EFE.
"We will obviously try to beat them, but it will be very tough. They are one of the best teams in the world and play some great football.
"We have some great players as well, though, and we have been in fine form in the league."
Tuesday's encounter is scheduled to kick off at 18:00CET.
