Emery's philosophy will be put to the test immediately this season as his side takes on champions Manchester City on Sunday.
Emery is convinced the Gabon global can win the Premier League's Golden Boot this season.
Kevin De Bruyne is fit enough only for a place on City's bench having returned to training after the World Cup this week, while Sergio Aguero is preferred to Gabriel Jesus after the Brazilian failed to score at Russian Federation 2018.
'The pre-season is the same opportunity, the same chances for the goalkeepers.
When asked if City had fashioned a ideal performance, Guardiolan told the BBC's Match Of The Day: "Yes".
"Many players did a sacrifice, Stones, Walker, we trained for only one week but the spirit is there". We made a good performance in general and day by day we will get better and better. "But I think this process today is normal, especially against a team like Manchester City".
The City boss started with Kevin De Bruyne and Leroy Sane on the bench as he recalled Sterling and gave a Premier League debut to Algeria winger Riyad Mahrez, whose move from Leicester was Guardiola's only major close-season signing.
For City, it's a lovely start away from home and it shows that even this early in the season, this team is once again the favorite to win the league.
Ainsley Maitland-Niles came on for Kolasinac after he was hurt in Arsenal's 1-1 draw with Chelsea on August 1 and Emery said following the match he would not rule out using the 20-year-old against City.
MF Aaron Ramsey, 6 - It was a big boost to Arsenal to see the Welshman passed fit, and he was the man charged with spearheading Arsenal's new pressing system. A golden moment for Aguero to double City's advantage. but the Argentine makes a mess of it!
In the end it mattered little.
Whereas other sides are struggling to find 11 fit players because of injuries and World Cup hangovers, Arsenal seem in decent shape for the new campaign. "Second half we got better". Unfortunately, we lacked invention to find the killer pass.

Thus, he is definitely a huge threat for the Manchester City defence, likely to be led by English worldwide John Stones. It's about the mix, when you have a defensive or attacking moment, and I want every player to improve in this way.
