The prolific attacker enjoyed watching the former Gunners star in his Premier League years, and has hailed Dortmund coach Jurgen Klopp's energetic approach
The former France international was widely regarded as one of the best players around in his heyday, and the 24-year-old kept a close eye on his performances for the Gunners.
"I didn't have one particular idol, but there was a player I tried to follow. It was Henry in his time at Arsenal," Lewandowski told Uefa.com.
"I liked the way he played and moved on the pitch. I think he was a great player."
The Poland international also had his say on BVB coach Jurgen Klopp, and praised the 45-year-old's passionate approach.
"You can see on television how happy he is when we score, and how mad he gets after a failed move – but not with us, but rather with the ball not going into the goal.
"I think he lives and breathes not only the matches, but also the training."
Dortmund are currently preparing for Tuesday's Champions League match away against Ajax.
