IMO, Lacazette doesn’t have the technical qualities to play as SS/CF. He is a pure ST although not a very good one. 3-4-3 won’t solve anything because Aubameyang will still be shifted out wide. 3-5-2 was the hottest formation in the league when Conte destroyed the league with it, but it has surprisingly gone out of fashion lately. I would really like Emery to give it a try before he gets sacked.
