The two teams will meet in the first leg of their Round of 16 tie at Parc des Princes on Tuesday night and despite the gaping difference in their domestic league positions, Courtois is confident the Chelsea attack can do some damage in the French capital.
He said: "I'm sure it'll be like the game here last year. We'll have to defend well, but also we'll have to show our quality when we have the ball and try and make in-roads as an attacking side ourselves.
"Last year we had a difficult game here as well. With (Angel) Di Maria they've added quality to their team.
"In the league they're doing very well and will win it. It will be a difficult game for us, but hopefully also for them.
"We have the quality to cause them problems."
