Mkhitaryan passed up a couple of shooting opportunities as Arsenal resumed on top but Milner broke the deadlock, smashing home when Leno's fumble from Mane's cross deflected into his path off Rob Holding.
So what's missing? Apathy, for one. Xhaka's passing range was to the fore as well over 90 minutes he appeared to enjoy, now freed from his recent toils as an emergency left-back.
A whipping boy when Arsenal fell short against Premier League heavyweights last season, Switzerland worldwide Xhaka displayed all of his enviable array of qualities, often leaving Liverpool disorganised in central areas as a result.
Will both teams score goals on Saturday?
When Paul Merson came out on Sky Sports during the week and said that he thought Arsenal would get whipped by Liverpool at the Emirates on Saturday, I knew all was not right with the world. It was a collective effort, one which Emery played his part in with his passion on the touchline, and Arsenal deservedly levelled to claim a draw.
"A point at Arsenal will always be an absolutely good result, so we take that and move on".
"For our result, this point is not enough", Emery said. "They are a very good example for us".
"I think we made more mistakes than the refs, but in this situation, it would have been cool if this goal would have count", Klopp told BT Sport.
Gunners manager Unai Emery, celebrating his 47th birthday, was also content with the performance and even happier that his side improved on their previous displays against the top teams. The team is largely the same as a year ago, with only goalkeeper Bernd Leno and midfielder Lucas Torreira starting this game, having arrived in the summer. It's up to him to prove he can make the necessary improvements in his game. The Uruguayan is the defensive midfielder Wenger's teams had lacked for at least a decade, and he has brought tenacity, vision, energy and a smart football brain to Emery's Arsenal.
Torreira has been hugely impressive in the way he recovers possession.
But Emery spoke in the build-up to this contest about wanting to write a new history for Arsenal and in this fixture there were signs his players are embracing the new era, which will have been a pleasant birthday treat for their boss.
Arsenal haven't led at half-time in any of their 11 Premier League matches so far this season.
