The two teams will meet in the Champions League semifinals.
Marcelo said: "Lewandowski is tough and is a hard man to defend against. The whole team is very strong, we don’t think about any single player and we will see what happens because we really want to reach the final. We are doing well and are very focused.
"We are united in the dressing room and it shows on the field. I hear lots of talk about The Tenth (European Cup win). It is a dream for the fans, the first thing that we’re dreaming of is being in the final and taking it step by step. We have a great opportunity and we’ll have to see if we can do it."
