Giroud scores the dramatic victor to save Arsenal, a simply sensation moment and Leicester has their hearts broken again against Arsenal with a late goal scored against them.
"Obviously I knew that I was going to have a chance so we tried to push", Giroud said.
"I opened the door for him at some stage [to leave], because I know that it's important for him to play", Wenger said in his postgame news conference.
Vardy weighed in with two superb goals in a virtuous man of the match display.
It was an incredible escape act from Arsenal, but Giroud claimed his team, who dominated possession and peppered the Leicester goal, never doubted they would hit back.
"This has happened to us the last three seasons here". It was a relief for me he made a decision to stay.
Arsenal rally late to defeat Leicester on opening night
Cech, who holds the Premier League record for clean sheets, admitted that conceding three goals at home was not "an ideal start". Lacazette slipped as he went to turn and shoot and scuffed his shot to Kolasinac, who found himself one on one with Schmeichel.
"Giroud? He's fantastic", Wenger said of the France global, who usually started on the bench last season and had been linked with a move away from The Emirates.
Typical Arsenal though, they conceded an equaliser just three minutes later when Harry Maguire headed back across goal excellently for Shinji Okazaki to nod home past a hapless Peter Cech.
With the first Premier League match in the books this term, how did pundits, supporters and players react on Twitter to Arsenal versus Leicester?
The 67-year-old manager praised his side's spirit after their comeback win and admits that there is work to be done in defence after letting Leicester score from two set-pieces. He'll play 30 games, he'll give you 15 goals.
"Disappointed the referee didn't give it because he had a great view but then we have to defend the corner given", Shakespeare was quoted as saying by the Independent.
The overall experience pleased the forward, who admitted that he is still getting used to a new style of game at the Emirates Stadium.
"After that, we get the efficiency".
