Kanchelskis doesn't rate the quality of Chelsea's players this season.
"This year, Chelsea are not such a strong team, as they were a few years ago," he told Izvestia.
"The club is in a change of generations, and the owners cannot determine the future of the coach. Because of this, the team is under constant pressure.
"In contrast, Kazan is very balanced and the coach has clear ideas. Ruby will not run headlong forward, and will wait for their chance. I think that Rondon can score an important goal on the road. The Venezuelan is in great shape."
