However, there was one more twist in the tale as Olivier Giroud came off the bench to snatch a victor in the 86th minute as his header from a late corner came off the bar and dropped over the line to secure Arsenal a dramatic 4-3 win.
Granit Xhaka's casual pass to Ramsey was masterfully flicked past Schmiechel - two minutes later, the attacker Olivier Giroud, who came in the 67th minute, scored the winning goal, lifting the Gunners to glory.
"We saw it though for 83 minutes", Leicester manager Craig Shakespeare said, "and to concede two late set-plays in the manner we did is obviously hard to take".
Such an effort provoked scenes of sheer jubilation at the Emirates Stadium and came just two minutes after fellow substitute Aaron Ramsey looked to have rescued a point for the inconsistent Gunners after blasting in from close range. "(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".
Giroud appears willing - if a little reluctantly - to accept his role as an understudy to Lacazette.
Alexandre Lacazette marked his Arsenal league debut with a goal on 94 seconds, only for Shinji Okazaki to level less than three minutes later. While Lacazette has started with an impressive performance in the Community Shield match, Kolasinac went a step further to score the all-important equaliser leading to the Arsenal win in the Community Shield.
Although Wenger admitted that entering the new campaign without Sanchez is a big blow for Arsenal, he pointed out that the striker would not have featured against Leicester even if he had not sustained the injury.
"He is really loved here, we love him and, in the end, he made a decision to stay".
"We were quite good past year on corners and I believe with a bit of work, we can get that out of the system". "Yeah, we have top quality". Leicester re-took the lead on 58 minutes, with Vardy heading home Riyad Mahrez's corner. "He is focused and happy in the dressing room because we won the game".
