"There were seasons where you felt like we were in with a shout but then through various circumstances it wasn't to be", he said.
Aubameyang made way for Alex Iwobi as the game headed towards its final 20 minutes with the home side and control and Everton's spark having deserted them.
He also likened Arsenal to golfer Tiger Woods who, despite winning his first tournament on Sunday for five years, won the last of his 14 major titles back in 2008.
"What we lacked in the past - I would say the "Arsenal way" was more important than getting the points sometimes and this is not how you win the league".
"Then we scored the goal and I made a decision to stop it and think again about who we need next".
"Today he showed us that he's very good and continuing to work hard with this spirit every day".
The Toffees actually begun the match well and had numerous chances to take the lead in the first half with a combination of poor decision making, some ordinary finishing and a strong showing from Gunners keeper Petr Cech all uniting to keep the Merseyside outfit at bay.
A top four finish in the Premier League would insure that Arsenal once again compete in Europe's top club competition after a two year absence and Emery did not play down its importance.
After a shaky start this season which has seen several key players struggle to adapt to the new style, Emery's men have seemingly found their feet and won their past three games. "That will make the big difference".
Arsenal now switch their focus to League Cup affairs and their home clash against Brentford in the third round on Wednesday night.
"I gave him all the information I could to try and help him out during his period of settling in and I think he's very happy and I think he's a great manager for Arsenal. We deserved really more", Silva told reporters. The first half performance was woeful at times but the Gunners stayed in the game and got the goals when they needed to. The Championship is a brutal league and you can get beat like we did on Saturday if you don't turn up.
They had a glorious chance to take the lead inside 90 seconds as Dominic Calvert-Lewin broke behind Arsenal's high defensive line.
"We will respect Arsenal, but we won't fear them".
"But we are in a different place now in terms of belief and how we can play".
