That escalated quickly.
Despite shipping plenty of chances to Leicester in the first 60 minutes when Arsenal turned it on they really turned it on.
Mesut Ozil put in a captain’s performance, Pierre-Emerick Aubameyang was clinical in the extreme but their most potent attacking threat was Hector Bellerin.
The Spaniard will have an unfortunate own goal to his name after Ben Chilwell got the better of him in the first half, but other than that he put in a flawless display.
Unai Emery’s system implores the full backs to push right up the pitch and offer a danger on the wing in Bellerin they have the most in-form right backs in the league.
Kyle Walker who?
Time after time against Leicester Bellerin was seen bombing down the right wing with Chilwell having a difficult night containing him.
His Arsenal team-mates know that he is constantly going to be making that run and can release the pass almost telepathically.
Over the last couple of years Bellerin has flattered to deceive at Arsenal, going from Spain’s right back to a symbol of Arsene Wenger’s decline.
But this season he looks razor sharp and at the top of his game – this match proved that he has returned to the big time.
Ozil was whirring in midfield but every time he had the ball he was looking for Bellerin on the overlap which proved to be incredibly effective.
Bellerin set him up with a perfect return on the one-two for Arsenal’s first goal.
For the second it was all about Bellerin again – he burst into the Leicester box and was found by an inch-perfect ball from Ozil, demonstrating sheer pace and awareness he squared the ball for Aubameyang to tap in.
I don’t know if we can call it Wengerball anymore but this was as good as it gets.
Again for the third, Bellerin was the outlet on the right wing as the Gunners broke.
He played it in to Ozil and the rest was a penalty area masterclass.
It wasn’t just for the goals that Bellerin destroyed Leicester.
As soon as the Gooners came out for the second half it felt inevitable that we would soon see Bellerin cutting it back for one of the strikers to tap in.
In almost no time at all Aubameyang had done it twice.
The right back has already notched a career-best four league assists this season and we are only nine games in.
He is officially back.
