Liverpool were denied an initial goal by the most slender of margins when Roberto Firmino struck the post and allowed Sadio Mane to tap in, but the Senegalese was deemed offside - perhaps controversially - by the assistant referee.
Two of the Premier League's three remaining unbeaten sides will be in action on Sunday, when Manchester City and Chelsea attempt to match Liverpool's 11-game unbeaten run to start the season. "They're not in the same class as this Liverpool team", Merson said on Gillette Soccer Saturday.
In fact last season, one would have to look all the way down the table to 15 placed Brighton to find the first team that drew more times than the Reds, whose 12 stalemates were an equal third highest, and they already have just one less (three) than Southampton's league high of four.
Further forward, the talented but frustrating Mesut Ozil and Henrikh Mkhitaryan continue to blow hot and cold, but the two flair players at least now put a shift in for the team and play with a sense of goal. And with Emery owning the technical area and patrolling the touchline like an over-competitive parent, the sight of Arsene Wenger looking on with his hands in his pockets and out of ideas has also been consigned to history.
DF Shkodran Mustafi, 7 - Was near flawless for the opening hour but questions can be raised about his role in Liverpool's goal as well. He came out to try and clear a cross, but instead of catching or punching the ball, he played it into the path of the Englishman, who was never going to miss.
"If you remember, when I scored a goal against West Ham earlier in the season I was offside and that goal counted".
"The reaction of the team was flawless", goalkeeper Bernd Leno told Arsenal's official website afterwards. Helped control the game and finally looked like the midfield general Arsenal need him to be.
So what's missing? Apathy, for one.
Arsenal may have ridden their luck at times, especially when Mane's first-half strike was incorrectly ruled out for offside, but fortune favours the fearless and the signs are there that Emery has imbued the Gunners with a new spirit. But Lacazette rescued his team thanks to a brilliant strike.
The Reds took the lead through captain on the night James Milner, who also netted his 50 Premier League goal, but the Englishman was more disappointed that his side let the advantage slip.
"I believe we were the better side today and that's how we must continue".
MF Danny Welbeck N/R - Injected pace and energy as a late sub and helped create some late chances for the victor.
