The Gunners head to Fulham looking to jump back up into third place in the Barclays Premier League, with fellow Champions League contenders Chelsea and Tottenham not in action until Sunday.
But for some more clinical finishing from Giroud, Arsenal could have seen off Everton's resolute challenge in what was a bruising goalless encounter at the Emirates Stadium on Tuesday night.
Wenger, however, feels the France striker, 26, will only improve as he learns quickly from a first season in the English top flight after a £13million summer move from Montpellier, where his goals had speared them to a first Ligue 1 title.
"Giroud gave a lot until now and for his first season he is doing extremely well because he has a fantastic attitude, he is a positive mind," said Wenger, who reluctantly agreed to sell captain Robin van Persie to Manchester United during the summer which severely depleted Arsenal's frontline.
"He is a little bit less (like) the strikers we used to have until now, but he gives us another dimension with the physical challenges in the air.
"Olivier has good physical potential, has a good basic stamina and he can absorb the games. He can absorb the body to body (challenges) because he's a strong guy.
"He wants to do well, but is not the one who hides afterwards. He stands up for what he has done and I feel he deals quite well with that.
"Giroud has scored 17 goals in all competitions, 11 in the championship, for a first season that is quite good. I think you will see more from him next season, and there is a lot more to come from him."
