The Gunners also asked questions as an Alexander Lacazette's shot narrowly went wide after a lovely build up play from Mesut Ozil and Pierre-Emerick Aubameyang.
If insane things happen then maybe we have to think new but I don't expect that.
Two minutes later, Sadio Mane felt aggrieved at seeing his tap-in ruled out for offside. You have one player in the slightly-offside position and then the other one takes the ball.
Liverpool fans knew from the moment the midfielder fired home a second-half goal to put the visitors ahead in the capital, that the club would simply not lose the game, and that proved to be correct. After losing their first two games of the season, to Manchester City and Chelsea, this was their first chance to test themselves against another side expecting to finish in the top four.
Klopp conceded it was an "intense" encounter but declared it a good result.
Arsenal deserved a point from what, given the opposition, was arguably its most impressive performance of the season and it came thanks to one of Emery's substitutions: Alex Iwobi, who drifted in from the left and played a terrific ball through to Lacazette.
It was always going to be a challenge for Jurgen Klopp to replicate the incredible season his Liverpool side enjoyed last season.
Good managers and coaches make their players better, inspiring them to perform with greater intensity, and the greatest compliment for Emery is that he is transforming several members of his squad, many of whom had been written off as no-hopers during the final days of Wenger. We needed a little luck in some moments of the match and also we needed, when we were attacking, to find our goal.
No team will be able to completely contain Liverpool's high-powered attack for 90 minutes but Milner's opener still felt a bit unnecessary.
"It was a hard one because we took the lead and this season we've been really good at holding on to leads".
"It is not a bad point but we need more". But the spirit is like we want. In the three matches (Liverpool, Manchester City and Chelsea), this was a more complete game for us.
But the fightback extended Arsenal's unbeaten streak to 14 games and showed they are ready to compete with England's top sides again.
The Premier League is of course awash with top talent, with the top six sides possessing an embarrassment of riches in nearly every department in the field.
