He said: "I had at Valencia, Villa and Morientes, I had (Roberto) Soldado and (Aritz) Aduriz; I had in Sevilla (Kevin) Gamiero and (Carlos) Bacca, I had at Paris Saint-Germain, Cavani and Mbappe. Here I have Aubameyang and 'Laca'. It's perfect.
"Sometimes you need to play both, with two strikers, and sometimes you can play with one player wide, and sometimes you can play with another on the bench.
"I have the habit to have two strikers, or three strikers. Also in Spain at Sevilla I worked with Bacca, Gamiero and Iago Aspas. Three strikers. I want to play and have the best players. Here, with Aubameyang and Lacazette I am very happy with them."
Emery suggested goals are his only focus when it comes to working with strikers: "In training I said to them, 'When I have one ball, in training, I imagine you'll score one goal, every time. Score, score, score'.
"That's my mentality - I push them with this mentality. That's the best development for them and for the team.
"Each striker has his qualities and characteristics, but one is similar. They are strikers and score a lot of goals. All of them. That's Villa, Negredo, Carlos Bacca, Gamiero, Cavani, Morientes, and Soldado, and now here Lacazette and Aubameyang."
