The Portuguese outfit meet the Bhoys at Celtic Park in their Group G opener on Wednesday and star striker Cardozo is prepared to put his body on the line against the likes of Charlie Mulgrew, Kelvin Wilson, Mikael Lustig and Thomas Rogne.
"These games are very competitive for me - I will have to battle and fight against the Celtic defenders," he told SunSport.
"But that's not a problem. I am always comfortable in these situations.
"We don't need to change. We must control the game and try to create danger. Any other style is not the real Benfica."
