The Blues travel to Denmark having been handed arguably the easiest possible draw for the knockout stage, with their opponents rookies at this stage of the competition.
That was in stark contrast to Arsenal and Spurs, who were dealt the toughest of fixtures in Barcelona and AC Milan, respectively.However, the north London rivals both produced stunning victories to give them real hope of progressing to the quarter-finals.
Tuesday night sees the spotlight fall on Chelsea, who began another season as one of the favourites for the Champions League and will be fully expected to reach the last eight.
Asked if there was extra pressure on his side in the wake of Tottenham and Arsenal's exploits, Blues boss Ancelotti said: "Not extra pressure but we know Copenhagen very well.
"They are a good team, with fantastic organisation, a dynamic team, they use a lot of speed.
"It's important to know this to prepare well for the game, and to have courage to play."
He added: "Tottenham and Arsenal played a fantastic game.
"They reached a fantastic result against Barcelona, against Milan.
