Sevilla boss Unai Emery is not underestimating Zenit, despite the Russian side being without the services of some key players.
Sevilla will approach Thursday's UEFA Europa League tie against Zenit with caution, even though the Russian Premier League leaders look set to be depleted.
The sides meet in the first leg of their quarterfinal at the Estadio Sanchez Pizjuan, with Zenit manager Andre-Villas-Boas without the suspended quartet of Domenico Criscito, Danny, Hulk and Igor Smolnikov.
Viktor Fayzulin is also doubtful with a knee problem, but former Spartak Moscow coach Emery warned his defending champions of the quality Zenit still has at its disposal.
