Speaking with Sport1, Lewandowski spoke of pride at his Barcelona presentation.
"I didn't expect so many fans. It doesn't matter if he had more or less than other players presented before by Barcelona like Ronaldinho or [Zlatan] Ibrahimovic," the former Bayern Munich striker said.
"Those were different times anyway. It's very nice when you experience so much support directly. It's something that stays with you forever.
"I always wanted to play in LaLiga, that was clear to me. And when Barcelona came knocking on the door this time, they were the only option for me.
"There were other offers, but I wasn't interested."
