The Blues earned a 2-0 win at Stamford Bridge on the night, giving them a 3-1 triumph on aggregate.
Despite a number of European heavyweights still left in the competition, Cech is not concerned by who Chelsea are pitted with in the draw for the last eight.
"I don't have any preferences for the next round," the goalkeeper told the club's official website. "You can't really choose opponents when you get to the quarter-finals so let's see what the draw will bring."
Chelsea return to Premier League action on Saturday when they play host to title rivals Arsenal.
