While the Gunners ultimately went on to lose the resulting penalty shoot-out, there was much reason to be optimistic ahead of the new Premier League season.
Boss Emery insisted ahead of the game that he would pick his starting line-up for the clash against Real with the first game against Newcastle on August 11 in mind.
For Arsenal’s previous pre-season matches the Spaniard opted to start with an array of young talent before bringing on his more senior players later in the game.
But the likes of Pierre-Emerick Aubameyang, Alexandre Lacazette, Mesut Ozil, Henrikh Mkhitarian, all started against Real Madrid.
Other first team players such as Granit Xhaka and Sead Kolasinac also returned to the starting line-up.
Joe Willock, Calum Chambers, Carl Jenkinson, and Emiliano Martinez also played from the beginning.
And apart from replacing Wilock with Nacho Montreal at half-time, Emery opted to keep his starting eleven on the pitch for all of 75 minutes against Los Blancos.
Youngsters Robbie Burton, Reiss Nelson, Bukayo Saka, and Edward Nketiah all then came on with 15 minutes to go.

So which two players who are not guaranteed to play from the start against Newcastle best stated their claim to get the nod?
First, a big mention has to go out to midfielder Wilock.
The 19-year-old, despite only playing 45 minutes against Zinedine Zidane’s men, put in an assured display against the experienced Toni Kroos in the centre of the park.
Wilock has impressed from the start against Bayern Munich and now Real Madrid in recent days and could push for a place in Emery’s line-up for the opening Premier League game at St James’ Park.
Another player who needs to be given more chances to play from the start of matches is Lacazette.
While the Frenchman did feature in most of Arsenal’s matches last season, many think that he was sometimes used too sparingly.
His 19 goals was a solid return for a player who in many games came off the bench in the second-half.
But his combinations and link-up with star striker Aubameyang is now looking too important to waste going forward.
The pair combined again brilliantly for Aubameyang to score Arsenal’s second goal against Real Madrid.
Emery’s problem in the past been trying to fit both players into the formation that he wants to play at times.
It remains to be seen whether things will change going into the new season.
