Giroud came big for the Gunners once again.
"But at some stage I opened the door for him because I knew that I had many strikers".
"It was one of the great days".
"Not only as a player, he is a fantastic player, b ut as well in the group - he has a big weight in the squad and it was a relief for me that he made a decision to stay".
"We kept going and the spirit of the team was absolutely outstanding", Wenger said.
It didn't take long for things to get started, with Alexandre Lacazette giving Arsenal the lead in just the second minute of his debut as the most expensive signing in the history of the club. "He did very well on the left when we moved him. We were a threat and played football and contributed to a thoroughly entertaining game".
Despite only starting 17 games last season in all competitions, Giroud still scored 16 times - including an eye-catching scorpion-style kick against Crystal Palace.
But the French coach knows he has work to do on his defence after Friday's performance in which Arsenal were found wanting at two set pieces that resulted in Leicester goals. "(We had) 70 percent possession, 27 shots on goal, Leicester had three shots on target and scored three so that shows you how efficient they are".
The 30-year-old has been linked with the likes of West Ham, Everton and Marseille since the arrival of club-record signing Lacazette but Wenger is pleased the former Montpellier man has opted to stay put.
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.
