This is according to midfielder Stoke & # 39; and Manchester United legend Darren Fletcher.
Arsenal drew 1-1 with Liverpool in the Emirates, thanks to Alexandre Lacazette leveling 10 minutes before the end.
Gunners are now undefeated in their last 14 games in all competitions since their 3-2 defeat at Chelsea in August.
The only other loss that Emery has so far experienced as the head of Arsenal was the opening day of the season against the reigning champions of Manchester City.
And Fletcher claims that getting a point against Liverpool calms down the doubters after these two early failures.
"I think it's huge, even though it's just a draw, obviously coming from behind," he told Sky Sports.
"But at the back of the Chelsea and Man City games, where they lost and people said" old arsenal. "
"Of course it was early in the season, but since then they've been successful and they look like they've improved.
"So I think it's second to none and I think it was a positive performance against Liverpool's very good side."
Emery clearly instructed his players to play in the first months as the head coach.
And Fletcher believes he is back in a similar style with which Arsene Wenger played a few years ago.
"I think so (there is a little more about Arsenal)" – he continued.
"I think they look much more organized.
"It seems to me that Arsenal has always been free and open, but I think that now there are some more structures in it, of course he wants to play in the back.
"There was a time when Arsenal escaped from this, even though we're talking about Arsenal as this nice football team, they were running away from playing the goalkeeper, and they chose a direct and long time and played on.
"So I think that there is a new style and it seems that they are improving and I was impressed."
Arsenal returned on Thursday in a match against the Europa League, when the hosts of Lisbon Sporting in Emirates (20.00).
