The Gunners eventually ran out 4-3 winners following an entertaining encounter at the Emirates Stadium. Yes, they looked shaky at times in defense with Lacazette and Welbeck combining well in and around the box, but most teams struggle with that against Arsenal.
Giroud came off the bench with Arsenal trailing 3-2 in Friday's Premier League curtain-raiser at the Emirates Stadium and after fellow substitute Aaron Ramsey equalised, he headed in an 85th-minute victor.
"Obviously for the neutral it would've been a great start, just watching it from the outside", the former Manchester United striker said. And in the end he chose to stay and it was one of the great days of the recent weeks for me.
Still, not the ideal start for Shakespeare as a manager who has spent plenty of cash ahead of first full season in charge in the Premier League. They have won only once in their last seven opening-day games - a 2-1 victory against Crystal Palace in 2014 - and have not lost three consecutive opening-day games since 1960.
"That's what we're aiming to do", he added. Arsenal looked unable to handle us at the back, but Leicester in turn couldn't string more than a couple of touches together before giving the ball right back.
In general, Arsenal will have the upper hand because they play at home. This one was back and forth like a classic title fight.
"At one stage I opened the door for him as I knew I had many strikers, and in the end he made a decision to stay".
"But as much as I can I will try to help the team to reach our target and tonight we needed this win as everybody knows the importance of the first game for confidence and we keep going".
One of those was from playmaker Alex Oxlade-Chamberlain who, from the start, played the game with an attacking mentality and created a number of incredible chances.
