Despite many predicting Jose Mourinho's team to trouble outgoing Bundesliga champions Borussia Dortmund in the first leg of the team's Champions League semi-final tie, Jurgen Klopp's side ran out easy winners thanks to four goals from Lewandowski.
The 24-year old told polishfootballonline.com that Los Blancos will put up a stronger challenge in the second leg and it will be up to his team to prove that they deserve a place in the finals.
"If we don't play as well as we did in the second half, it will be difficult, Real Madrid is a fantastic club and will definitely push us to play defensively. We have to look to score in Spain - that will make our job much easier," Lewandowski said.
"We have to play just as well in the return leg to show that this wasn't an accident."
Although Dortmund were labelled dark horses at the start of the season, few expected to find them on the brink of a spot in the finals. Lewandowski revealed how shaken Real defender Pepe was after his goal haul in the first leg and admitted that his team were proud of their run in Europe's premier club competition.
"During one of the last corner kicks, Pepe came up to me and said 'You've scored four goals already, don't you think that's enough?" he shared.
"I am very proud but I think it will completely sink in after the season is over. We have made a huge step to make it to the final, but we are not there yet. I am very happy that we defeated Real Madrid in great style - especially in the second half where they had no chance against us. We played perfectly."
The second leg of the Champions League semi-final tie between Real Madrid and Borussia Dortmund will take place at the Santiago Bernabeu on Tuesday.
