Sevilla are in red-hot form going into the Group G meeting at Ibrox having won their last five matches in all competitions.
But former Tottenham stars Zokora and Kanoute are not taking anything for granted.
Asked if Sevilla were favourites to win the match,Kanoute said: "No, no. I don't accept that."
Zokora said: "I'm not sure because, in football, sometimes you play well, sometimes you play badly.
"I know the game is very difficult because Glasgow (Rangers) have a big stadium, a lot of fans. Glasgow are the best team in Scotland."
But he added: "I think Sevilla is better than Glasgow!"
Kanoute, whose goal saw Sevilla lift the UEFA Cup on their last visit to Glasgow two years ago, said: "It's going to be hard obviously, but we're quite confident. Hopefully, we're going to do something good."
Zokora was expecting a physical game.
"Of course, because I know the (English) Premier League, I know the Scottish league and it's very aggressive," said Zokora, who is looking forward to being reunited with another former Spurs team-mate.
"But there are a lot of good players like Pedro Mendes. I know him and he's a very good player."
Zokora feels Sevilla, who only trail Real Madrid and Barcelona in the Primera Liga, are good enough to win the Champions League.
"Why not?" he said. "This year is very important for the club."
