Having earned a first leg lead in the Champions League tie, Real must approach the return game in the same manner that they did back in Madrid, according to Ramos.
"We all know what the Champions League means to Real Madrid," the defender said after victory over Getafe. "We have to go to Paris with the professionalism and character that we showed in the first leg.
"We know it will be very tough, but we are clear about our objectives.
"We hope to face a great opponent. We have to put in our maximum effort and be as serious as here because we know that, in attack, their players are destabilising.
"But, we can also hurt them."
