The Russian side's trainer has admitted that his team face a tough task when they visit the La Liga leaders at the Santiago Bernabeu in Europe's elite tournament
Slutsky was full of praise for Los Blancos' forwards and stated that he expects Jose Mourinho's men to out in an aggressive and attacking display.
Nevertheless, the CSKA boss added that his side are not afraid of their opponents and will do their utmost to progress.
"Real Madrid are very dangerous. There's no way of stopping them from scoring goals. They are very fast in attack," Slutsky said at the pre-match press conference.
"Real will play at home and they are an aggressive side. The aggregate score currently favours them. We believe they will be very active and that they will not settle for a 0-0 score, which would also benefit them.
"A team like Real Madrid are capable of attacking down the wings and are very dangerous. We're not afraid, though, and our players are very experienced. Our objective is to reach the quarter-finals."
Wednesday's encounter at the Santiago Bernabeu kicks off at 20.45CET. The first leg in Moscow ended in a 1-1 draw.
