The 24-year-old got his first goal for Arsenal during the pre-season Amsterdam Tournament and comes into the English game as the record scorer in the Croatian league.
"I would not be scared to throw Eduardo in from the start," Wenger said. "He has settled in very well.
"Eduardo is a fighter, he can score goals, he is quick, he is a team player so you are never scared to put these players in."
Wenger added: "You know how big the pressure is on a striker - when he does not score for a while, they say 'What is he doing?' or 'Has he the level to be in there?'
"I remember answering the question for Thierry Henry. 'Okay, he created chances but do you think he can score goals?' - and he scored a few.
"So it is very important to score, but not for me, it is more to have a certain peace from outside."
