Adriano knows their first leg in Moscow represents a great chance to make further progress - especially with CSKA not having played a competitive game in two-and-a-half months.
"We cannot fail now," he said. "We are all very focused. The game is important for the players because everyone wants to play in the Champions League but it is also important for the club and the fans.
"Sevilla have grown enormously in recent years, are a team with strength and international presence and have to be in the Champions League to strengthen the position of the club."
"In the Champions League, everyone understands that Sevilla have great potential."
