"We have to take the positives out of the game, we have gone toe-to-toe with Arsenal over 90 minutes and I don't think many teams will come here and do that".
Giroud's Arsenal future had been subject to considerable doubt after five years, with the £46.5m ($60.4m) club-record signing of Alexandre Lacazette expected to restrict his starting opportunities even further.
That excitement was immediately transformed into celebration not two minutes into Lacazette's Premier League debut, as he bagged a pinpoint header to put the Gunners on top of Leicester City in the opening match of the new season.
Olivier Giroud headed home the late victor on Friday. "I opened the door for him, because I knew we had many strikers, but he's really loved here and he chose to stay".
"Not only as a player, he is a fantastic player, but as well in the group - he has a big weight in the squad and it was a relief for me that he chose to stay". Not only as a player, he's a fantastic player but as well in the group. It was a relief for me he made a decision to stay.
Giroud appears willing - if a little reluctantly - to accept his role as an understudy to Lacazette.
"I opened the door for him at some stage as it's important for him to play but I don't want him to go", Wenger said at the post-match news conference. "He doesn't want to leave".
Giroud was on the pitch for nearly half an hour against Leicester with the 26-year-old Lacazette, who joined from Lyon.
"It's simple, in every game he is stronger since he joined us", Wenger said.
'Tonight we needed this win, everyone knows the importance of the first game for confidence. Arsenal welcomed Leicester City into Emirates Stadium on Friday to get the festivities rolling this season, and it appeared as if everyone would get a chance to use their Arsenal jokes for at least the next week. Giroud himself said that he wanted to play but that he would "do a job for the team".
