The Spaniard will take charge next season after replacing Arsene Wenger, who spent 22 years at the helm.
And speaking at a fan event, the former PSG boss has revealed his plans to instil an attacking mentality in his squad.
"I prefer to win 5-4 than 1-0," said Emery.
"Why? Because I think football is spectacular, the best form is when you score.
"If we score more, it's better. I only want to score in front though [and not concede]."
