The Blues will have to subdue Lewandowski when Bayern travel to Stamford Bridge for the first leg of their Champions League last-16 tie.
But Lampard insists the German giants are far from a one-man show.
"It doesn't concern me," Lampard said in his pre-match press conference.
"He's been so consistent for years. His goalscoring record, everything about him from a distance is top class. I've watched quite a lot of Bayern and that shines through.
"He's the spearhead but they have a lot of threats. The levels have to go up in the knockout stages. The levels must go up everywhere."
