Real dropped two points against Levante, with coach Zinedine Zidane admitting errors cost them the draw.
"Can the mistakes we commit penalise us against Paris Saint-Germain? I do not think so. The Champions League is different," argued Varane.
"We will have a Liga match before then. We have a good team, we have confidence in ourselves.
"This team has shown that they are able to overcome such situations."
