For starters, Morata, Werner, and Lukaku come to mind. They were effective in their own right, but were never good choices to come here, and most people watching from afar knew that.
Secondly, when did Arsenal & United find this magical number 9? Are you referring to Lacazette and Cavani?
Finally, 8-9 goals from our highest paid player?
All things considered, Sterling has to be hitting double figures with ease.
