A goal each from Alexandre Lacazette and Pierre-Emerick Aubameyang helped the Gunners secure their second victory of the season.
Yet the fixture organisers didn't wait long in the season to give Arsenal a gruelling test.
Emery is eager to ensure that his side has a positive mentality going into the game.
Arsenal will make the trip to Anfield for Saturday's evening kick-off between the league's top two sides.
Liverpool is a fantastic team but they are not unbeatable and while it may be a tall order to come away from Anfield with all three points next Saturday, it is not impossible.
Probably a bit of a no brainer this one but if Andrew Robertson and Trent Alexander-Arnold are not stopped they will cause absolute havoc as they did all last season.
Jurgen Klopp's side are this weekend's opponents for the Gunners, and a positive result at Anfield could leave many dreaming of a potential title challenge.
He said: 'For us we don't want to play against Liverpool ever.
"Really our target is to reduce the distance [between us] and Manchester City and Liverpool last season, and when we go to play against them it's a big moment to show how [much stronger] we can be".
Sorry, Unai. That's not how it works.
'That is really our challenge, a really good test.
Unlike last season when they got their campaign off with back-to-back defeats to Chelsea and Manchester City. For a club of Arsenal's size, this is not good enough hence why the supporters are getting unnerved.
"We need all the players to show how we are going to make a big difference to previous year with the points".
Pepe's impact is very good.
"We are going to prepare first with the adaptation to them, their game plan and individual players and after to impose our game plan and capacity".
"It's the same if you ask if we are going to be stronger with those three players up front".
"I think first is to be positive in our capacity and then work hard".
'After we can win, we can lose.
Emery's positivity can only be a good thing as his team seeks redemption for last year's horror show.
