Wenger insisted after Euro 2016 that he would give his quartet of semi-finalists an extended break before returning them to the side.
Giroud was back in action for his national side in a 3-1 win over Italy in Bari on Thursday, scoring France's second goal in an impressive victory.
"My club situation? I'm not worried, I came back very late from the Euros," he said.
"It was normal to throw me in gradually. There is no problem on that side."
